The newest addition to our portfolio of solutions is the Comics Identification (/v2/comics_id). This service is designed to identify comics from images. While it’s still in the early stages, we are actively refining and enhancing its capabilities.

The API detects the largest comic book in an image, and provides key information such as the title, issue number, release date, publisher, origin date, and creator’s name, making it ideal for identifying comic books, magazines, as well as manga.

This tool is perfect for organizing and cataloging large comic collections, offering accurate identification and automation of metadata extraction. Whether you’re managing a digital archive or cataloging physical collections, the Comics Identification API streamlines the process by quickly delivering essential details. We’re committed to continuously improving this service to meet the evolving needs of comic identification.

Star Wars Unlimited, Digimon, Dragon Ball, and More Can Now Be Recognized by Our System

Our trading card identification system has already been widely used to accurately recognize and provide detailed information on cards from games like Pokémon, Yu-Gi-Oh!, Magic: The Gathering, One Piece, Flesh and Blood, MetaZoo, and Lorcana.

Recently, we’ve expanded the system to include cards from Garbage Pail Kids, Star Wars Unlimited, Digimon, Dragon Ball Super, Weiss Schwarz, and Union Arena. And we’re continually adding new games based on demand. For the full and up-to-date list of recognized games, check out our API documentation.

Detect and Identify Both Trading Cards and Their Slab Labels

The new endpoint slab_grade processes your list of image records to detect and identify cards and slab labels. It utilizes advanced image recognition to return detailed results, including the location of detected items and analyzed features.

The Slab Label object provides essential information, such as the company or category (e.g., BECKETT, CGC, PSA, SGC, MANA, ACE, TAG, Other), the card’s grade, and the side of the slab. This endpoint enhances our capability to categorize and assess trading cards with greater precision. In our App, you will find it under Collectibles Recognition: Slab Reading & Identification.

The post New AI Solutions for Card & Comic Book Collectors appeared first on Ximilar: Visual AI for Business.

Today, I’d like to introduce a solution specifically designed for physical stores and warehouses to process their physical card collections quickly and efficiently using card scanners like those from Fujitsu. This tutorial is tailored for shop owners who need to handle large volumes of card images rapidly. We’ve developed a simple yet powerful script in Python 3 for card identification, condition assessment or grading. It also identifies comic books and reads slab labels from companies like PSA or Beckett. The script outputs a CSV file that can be easily imported into Google Sheets or Microsoft Excel. With a few modifications, it can also be adapted for use with your Shopify store or other seller tools, such as for eBay submissions. Let’s dive in and see how this tool can streamline your card-processing workflow!

Capabilities of our AI Solution for Sports Cards and TCGs

Trading Card Games

In the previous blog post, I wrote about our REST API for identifying TCGs, sports cards, and comic book covers. The TCG identification service supports more trading card games, including the most popular ones like Pokémon, Yu-Gi-Oh!, Magic: The Gathering, One Piece, and Lorcana. For some games, it can also identify the correct language version of the card or determine if it is a foil/holographic card. Additionally, for certain TCG games, the system provides links or identification numbers to the TCG Player. You can try how it works here.

Sports Cards

For sports cards, we can identify more than 5 million trading cards across six main sports categories: baseball, hockey, football, soccer, MMA, and basketball cards. Our system also supports the identification of parallel and reprint versions, with continuous improvements. Not only does it provide the best match, but it also offers alternative options to choose from.

If the trading cards are in slabs from major grading companies like PSA, Beckett, CGC, TAG, SGC, or ACE, the system can instantly identify graded cards and provide the slab company, grade, and certificate number.

All Under One API

As you can see, the functionality is complex, offering features such as bulk trading card scanning and language support, resulting in highly accurate identification. I believe that Ximilar Collectibles Recognition services are the most accurate solutions available on the market today. It is a true game-changer for card dealers, other collectors, or companies looking to be independent of third parties like CollX, Kronozio, or Card Dealer Pro, which automatically submit your cards to their marketplaces.

With Ximilar, you can handle your trading card scanning independently using our visual search technology and deep learning models. Our solutions are also designed to suit your specific needs through continuous improvements and customization. Whether you purchase, scan, analyze, search, or sell cards in bulk, our API empowers you to manage your collection without the constraints of third-party services.

How to Analyze TCG and Sports Card Scanners With AI

Step 1 – Run The Cards Through The Scanner

Enough talk! Let’s analyze the bulk of your cards. First, you’ll need a folder with images of your cards. For testing, I’ve selected a small MTG and Pokémon card subset. You can put them on your scanner via top loader (link), or individually. Most card collectors use the Fujitsu Ricoh Fi-8170 scanner, which is one of the best scanners available. It can capture both the front and back sides of the cards.

For our purposes, we will only need the front side of the cards. To avoid unnecessary costs, remove the back side images from the folder or configure your scanner to store only the front side of the cards. Some scanners, like Fujitsu, can produce scan files with names such as 19032024-0001.jpg or 19032024-FRONT-0001.jpg. You can specify the naming format for the scan files. See the following video tutorial on how to set up a Fujitsu scanner via PaperStream Capture by MaxWaxPax:

My recommendation is to use similar settings for your Fujitsu scanner as it is in the video by MaxWaxPax and create multiple profiles for sideways and top-bottom trading card scanning. Ideally set up the scanner to produce only images for the front of the cards or distinguish the images with “front” or “back” suffix in the filename. However, if you already have an unstructured collection of card images, you can fully automate the selection of images showing the front sides using our AI Recognition of Collectibles.

Step 2 – Sign Up To Ximilar Platform

Now, you’ll need an account in our App. Simply sign up with your personal or company email to get your unique API token for service authorization. Once you are in the App, copy your API key to the clipboard and save it into some file. To access the service via API, you’ll need to purchase at least a Business plan. Both tasks – getting the API key and purchasing a Business plan – can be completed in the platform’s settings in a matter of minutes.

Step 3 – Installing Python 3

Before running the script, ensure you have Python 3 installed. Some operating systems already include a version of Python, but we require at least Python 3.6. If you’re unsure, follow this tutorial on RealPython (link), which contains installation steps for Windows, macOS, and Linux:

You should be able to write in your command line, shell or terminal the similar command. Here’s mine at Mac:

michallukac@Michals-MacBook ~ % python --version && pip --version

If you don’t know how to run commands, read a short tutorial on using the terminal/shell/command line. I recommend this tutorial by DjangoGirls or watching some YouTube videos (here’s one for Windows and one for macOS). The output from the command should look similar to my example:

Python 3.9.18

pip 23.1 from /Users/michallukac/env/devel/lib/python3.9/site-packages/pip (python 3.9)

Next, you will need to install Python libraries argparse and requests via pip command:

pip install --upgrade argparse

pip install --upgrade requests

If everything passes, you’re now ready to use the script we’ve prepared to process your folder of card images!

Step 4 – Running The Script On Trading Card Games

Running the script is simple. You’ll need to use a terminal (macOS), shell (Linux), or command line (Windows), which is why we installed Python 3. Download the following file from one of these addresses:

• https://gitlab.com/ximilar-public/ximilar-client/-/blob/master/tools/process_card_scans.py?ref_type=heads

• https://gitlab.com/ximilar-public/ximilar-client/-/raw/master/tools/process_card_scans.py?ref_type=heads&inline=false

Put this file/script next to the folder (tcgscans) with your trading card images or scans and in the terminal, write the following command:

python process_card_scans.py --folder tcgscans --api_key YOURAPIKEY --collectible tcg --output results.csv --select_images all

Hitting the enter will execute the script on the folder of tcgscans, and the progress bar will be shown. The folder will analyze all the images in the folder (select_images). You can interrupt the script (it automatically stores the results every 10 images to your specified output CSV file):

Each analysis of a scan (sports card) will consume 10 credits from your credit supply in your Ximilar account. Our App lets you watch your credit consumption closely under Reports. The Business 100k Plan allows you to analyze 10,000 raw cards. If you need to analyze millions of cards per month or your entire collection at once, reach out to us, and we can offer you a bulk discount.

Step 5 – Analyzing the CSV file

Now we have our CSV file named results.csv. The CSV file contains the following fields: filename (name of the photo in the folder), status (ok or error), side (front or back), subcategory, full_name, name, year, card_number, series, set, set_code, and other additional fields.

The output format of the CSV depends on whether you analyze sports cards, TCG cards, comics, or slabs. Here is a visualization of the CSV file in Visual Studio Code:

We can import the file into Google Sheets or Microsoft Excel spreadsheet, edit it as needed, or generate printable checklists. The columns and data from the CSV can also be easily added to your Shopify product files or used for eBay submissions.

Additional information for card condition (or grading) can be added to the script via the –condition (–grading) parameter. For example, if your sports card scanner provides images with filenames such as 0001.jpg, 0002.jpg, 0003.jpg, etc., the following command will process images with odd numbering (e.g., 0001.jpg, 0003.jpg, …), identify the cards (name, card number, etc.), and also compute their condition (very good, excellent, etc.):

python process_card_scans.py --folder sportsfolder --api_key YOUR_API_KEY --collectible sport --output sport.csv --select_images odd --alternative --condition

Conclusion

With Ximilar’s AI-powered solutions, identifying and documenting your trading cards has never been easier. From trading card scanning, analyzing and organizing, to finding the current average market price, every step is streamlined to save you time and effort. I hope this guide helps you optimize your trading card workflow, making it easier to manage and showcase your collection. Happy collecting, whether it’s baseball or Pokémon cards!

The post How To Scan And Identify Your Trading Cards With Ximilar AI appeared first on Ximilar: Visual AI for Business.

We’ll look at companies developing interesting technologies for sports card recognition. Online card grading solutions (both offline and online, with AI and human graders), marketplaces where you can list cards, scanner companies that automate identification in big warehouses, mobile apps for managing and valuing personal collections, platforms for card investors, and special vaults for storing precious items can all benefit from automated sports card recognition.

Scanners for Sports Card Recognition

Card scanners are becoming very popular and there are tens of companies around the world with different pros and cons, features, capacity, processing speed, and pricing or subscription plans. All of them want to solve the problem of unmanaged warehouses full of cards.

TCG Sync – TCGSync is a very interesting startup that offers tools for cards like scanners (in partnership with Fujitsu), card catalogizing, inventory management, auto pricing and more. They support a lot of TCG types and have their own shop for card scanners that are ready for use. If you sign up for their yearly plan they will even give you a Fujitsu scanner for free and you can start selling on eBay, Shopify or Card Market from day 1.

If you already have a scanner and want to just identify the cards, you can connect to our API service with tools that will do it for you. Read more in my article How to Identify Sports Cards With AI.

Card Dealer Pro – This site is very similar to TCG Sync, but focused on sports cards. You just feed the cards to your scanner, Card Dealer will identify them with AI, propose a price for listing with title and description and publish them to eBay, Shopify or CollX.

Krono cards – This tool by Kronozio is for scanning and documenting your card inventory in bulk. It’s very similar to the TCG Sync and Card Dealer Pro. However, when you scan a card with a Krono Card, they directly submit it to their own marketplace. This can be a great advantage if you don’t have your own shop and a disadvantage if you don’t want actually to populate their database.

These are three main, but you can also explore several other options. For instance, TCG Machines is a Canadian company providing its own machine. Roca Sorter by TCG Player focuses on the four main TCGs: Magic the Gathering, Yu-Gi-Oh!, Pokémon, and Lorcana. CardCastle is an Australian company with its own scanner and platform to organize your collection. SortSwift is a system for managing your hobby store using the Ricoh scanner.

Sports Card Recognition & Evaluation With Smartphone Apps

Smartphone apps are really useful when you want to just check the card, its condition, or price on the internet. Here are the most popular ones that millions of collectors around the world use daily.

Ludex – A simple card scanner app that helps you identify the sports cards and get the prices using sports card recognition. After that, you can list it on eBay with a few clicks. In their free plan, you can scan up to 200 cards monthly. The plans are currently for 4.99, 9.99 and 24.99 USD enabling more functionalities like customized collections.

CollX – CollX is very similar to Ludex. With this smartphone application, you can snap a photo of your card and get its value in seconds. It’s the most popular smartphone app for card recognition and collection management. Also, the community is pretty active and you can easily submit a card to their own marketplace. It can tell the actual marketplace value and find similar listings.

Cardstock: Price Sports Cards: This app by Cardstock helps you with the identification and valuing of your cards. It’s designed for iPad and it can analyze baseball cards with great accuracy. This app is great for individual collectors, go and try it!

Collectr – Collectr is a great application for TCGs, that updates the value of the cards daily. You can manage your inventory and see the total invested value in the cards. I’m using the APP myself and the card scanning technology works great. My portfolio of cards is growing on value – it’s quite addictive

Sports Card Investor – It’s a great website with a smartphone app for everyone interested in investing in sports cards. You can see which cards are trending, you can search cards by complex queries, view recent sale prices and look at how the card is trending over the past. There are a lot of articles, resources, tips and also a very active community on Discord and social networks.

PSA Set Registry – This enables tracking your inventory of PSA-graded cards, seeing the populations and updating your own sets/collections. Basically, it is a gamification of collecting: you can compare your collection to others and compete on the leaderboard with your cards or get achievements or awards for collectors.

Online and Offline Card Grading Services

Card Grading is submitting and evaluating the quality and origin of the cards by third-party service with final sealing cards to the slabs. The grading usually increases the value of the cards (by demand) and makes the cards protected.

PSA, Beckett & CGC – There are several standard grading companies and the most popular are the PSA, Beckett and CGC. The PSA has the largest market share and the cards they grade generally have higher value than those from other companies. CGC first started with the comics but they are also doing cards now with currently refreshed labels.

Ace Grading – Ace Grading is a company from the UK with really cool slab labels. At this moment, they focus mostly on TCGs like Pokemons, Lorcana, or Magic The Gathering. This is a very good option for non-US citizens. The pricing is transparent with great support.

Tag Grading – Sometimes human graders can make a big mistake or can be very subjective during the grading process. Submitting to standard companies like PSA or Beckett can be very shady. That is why some companies try to develop grading based on computer vision. TAG Grading is a startup that develops its own technology for card grading. They use a scanner and AI models that can grade a card with accuracy, transparency and consistency. When TAG grades your card, you also get the grading report with an explanation of the grade. I think this is the way the grading should be done in future.

There are several online tools that you can use as individual collectors. For example, EdgeGrading provides a great web tool for getting the centering score. You simply upload the image of your card and adjust the Left / Right and Top / Bottom offsets.

SportscardsPro is also offering a centring web-based tool. However, the card photo cannot be scanned and there must be some background around the card. TrueGrade on the other hand is a smartphone app that grades cards based on the evaluation of centering, corners, edges and surfaces. A website alternative to TrueGrade is TCGrader – an AI-powered Pokemon grading system.

We built several useful tools for AI-powered sports card recognition, trading card game identification, card grading, and search. Read more in the articles and let me know what you think.

Online Platforms for Collectors

There are several platforms that can help you manage your collection, connect with the community, price the cards, sell them and much more.

Card Ladder – Card Ladder (by collectors.com) is a great platform for finding the value of your cards – including historical prices from several marketplaces like eBay, Goldin, Heritage or MySlabs and population reports. It also offers complex analytics and can track your collection. Personally, I like features like the charts of historical prices for my collection or notifications (price alerts) when some cards hit specified prices. They offer a free trial. Then, you need to subscribe for 15 USD/Month.

Price Charting – In my opinion, this is an awesome website, not only for trading cards but for comic books, video games, lego sets and coins as well. It offers you a search-by-photo functionality for selected card types/games. Our favourite function is an API for finding the value of ungraded or graded cards. The value for graded cards can be categorized per grade which many collectors consider to be the best source for price identification.

Collectibles.com – Collectibles are a quite new project with several interesting features. They have their own mobile application for iOS and Android. You can create your collection of cards, coins, stamps, memorabilia or comic books (with a showcase feature). The mobile app can scan and identify the items via AI-enhanced image recognition and add them to your collection. You can track the value of your collection so you can get better insights. Moreover, it has an active community where you can connect with other collectors, which is a big plus.

Collectors.com – Collectors are currently one of the largest market players (it is a site of Collectors Holdings, Inc.) when it comes to sports cards and trading card games. It has several divisions, one of them is a popular card grading company PSA. It also acquired companies like Wata Games. Currently, their app helps with managing your collections, selling them or sending them to PSA Vault. The PSA Vault is a cool service that helps you securely store your collector’s items with the opportunity to publicly sell them on their marketplace or on eBay.

Cardbase – Lastly, Cardbase is a platform designed for trading card enthusiasts to search, discover, and manage their collections. It aggregates prices and availability from over 30 marketplaces and auction houses, allowing users to track card values, view price trends, and find deals. Key features include comprehensive collection management tools, price tracking, and a mobile app for on-the-go access. Additionally, the site provides useful articles, guides, and resources for collectors.

Collectibles Marketplaces

If you are looking to sell your cards there are big sites as well as smaller ones, specialising in sports cards and TCGs. In general, you can always sell your card on eBay, but if you have a really expensive card then maybe you can try some auction house.

Sportlots.com – This is an amazing marketplace where you can get low-end sports cards very cheaply. In total, it lists more than 80 million cards from over 1000 sellers. The website has a kind of 90’s vibe but it has a lot of reputable sellers. Also, you can save a lot with their box system. That means that during the checkout, you can ship cards to your personal box and once you gather a good amount of cards you can ship them at once.

COMC.com – Check Out My Collectibles is a large marketplace and auction for all the card types. If you have more than a few hundred sports cards you should probably try to sell them via this marketplace.

Goldin.co – Goldin is a well-known auction house (goldin was acquired by eBay) that specializes in sports memorabilia, trading cards and sports cards. They are hosting high-profile auctions featuring rare and valuable items. The site is so popular that the founder Ken Goldin was featured in their own Netflix series King of Collectibles, The Goldin Touch. The Goldin is also a marketplace with tens of thousands of listings. Similar to the Goldin marketplace there is also PWCC which offers auctions, vaults and a marketplace.

The Most Popular Marketplaces

Cardmarket – This is originally a German company that offers a marketplace for your cards. It’s also the most popular marketplace in Europe. Just sign up and you can sell your singles, booster boxes or sealed products in minutes. It is very similar to eBay (each seller has a profile with reviews) but specialized in games like Pokemon, Dragon Ball, One Piece and others.

TCG Player – This is also one of the most popular marketplaces for selling trading card games (seller accounts), their marketplace supports a large number of games. The site was acquired by eBay in 2022. It has a lot of features, a mobile app, inventory management, and great customer support. They also offer developer tools like API for knowing the price of the card.

Japanese Card Marketplaces

In some cases, the Japanese sites can be very useful because cards are very popular in Japan and it’s a big market for sellers and buyers. So I picked a few that you should check out.

Cardotaku.com – is quite a great site developed for getting Japanese variations of cards. Started as a one-man business, and its popularity is growing. For the Japanese version of Magic The Gathering, we recommend checking Hareruya and Bigweb.

On TCG Republic you can find cards from various games. In general, I would recommend also checking out classic eBay and Mercari.com with their trading cards and collectibles sections.

E-Commerce Platforms

Do you need your own e-commerce solution with inventory management and many other features? Then try one of these platforms.

BinderPOS – BinderPOS is a solution that can run on top of your Shopify store and help you with the collectibles inventory. Originally from New Zealand, it quickly raised popularity among game stores worldwide.

CrystalCommerce – This is an in-store & online e-commerce platform for collectibles. A very similar solution to BinderPOS which helps you sell the stuff to several sales channels (such as eBay, Amazon, TCGplayer, and others). It’s easy to set up and you can pick from several website themes.

Storepass – Storepass is marketed as software for board games and TCG stores. It’s a generic platform on top of your e-commerce site like Shopify or BigCommerce. You can automatically access TCG market prices from TCG Player, manage your product inventory, edit the cards in bulk, and much more.

Other Projects

Lastly, I want to mention several other interesting projects, which do not offer typical services but can be very helpful for individual collectors.

For Card Pricing & Shipment

Mavin.io and Card Mavin – Mavin is a search engine for collectibles, you can get insights into what your collectibles are worth. Similar to pricecharting, they are offering the API for developers. So you can simply get the actual and historical prices for cards, comics or coins.

ShipMyCards – Shipmycards is an interesting project that can become your tax-efficient storage facility with your own USA shipping address. The main business is in the cards but they also support vinyl records, magazines, comic books, memorabilia, or even shoes. In general, you will get your own US address where you send your orders from eBay or other marketplaces. They will help you with collecting, grading, insurance, and final shipment. Great for people outside North America.

For Magic the Gathering and Other TCGs

Card Conduit – Have you found your collection of Magic cards from your teenage times and do you want to sell them? The card conduit is a really smart way how to sell Magic The Gathering in a very transparent and easy way. You simply send your cards via postage and they will price them and sell them for you. You exactly know how much you get for each of the cards because they can automatically identify them and get the best price for your cards. This is a very nice tool with amazing support.

META TCG is a project similar to Card Conduit but focused on Pokémon, Magic The Gathering and Yu-Gi-Oh! You just send your bulk submission via the post office and you get your payments via PayPal.

To Keep Up With News & Stats

CardLines – CardLines is a website where collectors can get information and read news related to sports cards, trading cards and other collectibles. The articles are released daily and if you are an active collector, this one is great to read. The site is trying to monitor the latest releases and there are a lot of tips for collectors. It also has its own small e-shop where you can buy some hobby boxes.

Universal Pop Report by Gemrate – is an amazing site for getting population reports and statistics of cards. The best thing is the grading stats for major grading companies – with this, you will know how many of the cards were graded by PSA or Beckett. In their blog, you can find the grading recap where you can find monthly statistics.

Sports Cards Calendar – This is a great way how to stay updated on upcoming sports cards. On the cardboard connection website, you can find checklists for almost all the sets.

Visual AI Infrastructure for Collectibles by Ximilar

Lastly, I would like to list the solutions we’ve been building for businesses such as collector marketplaces, comparison websites, card dealers, and their mobile applications. We are a SaaS company, focusing on AI, computer vision and visual data, so our tools can be used online via REST API.

Simply said, when it comes to AI for collectibles, we get quite enthusiastic. Currently, we provide:

• The most accurate sports card recognition API in the world – we can recognize parallels and holographic variants with great accuracy, and our growing database already contains millions of cards
• The most accurate trading card identification API in the world. For instance, we are achieving 99 % accuracy for Magic The Gathering, Pokemon and Yu-Gi-Oh!
• An online card grading and card condition system for smartphone cameras and scanners, also available via API
• Visual search and similarity systems for collectibles, which enable your customers to search your catalog of collectibles via pictures
• Product description systems (described here on fashion use case) – for automatization of submission of products on your marketplace
• Image upscaling system – the resolution of your images can be enhanced up to 8x easily
• Grading slab reading with OCR, which extracts the content of the slab, such as grade, the certificate number, year, and player and card name
• Background removal system – in case you need to exactly cut out the card

Our systems are built to analyze large datasets with speed & accuracy. They’re ready to use right away and customizable for specific image collections.

We are continuously improving the models, extending our sports card database and enhancing the speed of the recognition process. We are improving the parallels/refractors identification of sports cards, and our TCG identifier can manage language variations (US, Japanese, Chinese, Korean, …) and different editions (1st edition of Pokemons, MTGs editions). If you would like to help with an API integration, we are here to help. Just reach out via our chat or contact form.

Sports Cards Collecting on The Rise

Collecting sports cards, including hockey cards, has been a popular hobby for many people. Especially during my childhood, I collected hockey cards, as a big fan of the sport. Today, card collecting has evolved into an investment, and many new collectors enter the community solely to buy and sell cards on various marketplaces.

Some traditional baseball rookie cards can have significant value, for example, the estimated price of a vintage Mickey Mantle PSA 10 1952 Topps rookie baseball card is $15 million – $30 million.

Our Existing Solutions for Card Collector Sites & Apps

Last year, we already released several services focused on trading cards:

• First, we released a Trading Card Game Identifier API. It can identify trading card games (TCGs), such as Pokémon, Magic The Gathering: MTG and Yu-Gi-Oh!, and more. We believe that this system is amongst the fastest, most precise and accurate in the world.

• Second, we built a Card Grading and fast Card Conditioning API for both sports and trading card games. This service can instantly evaluate each corner, edges, and surface, and check the centring in a card scan, screenshot or photo in a matter of seconds. Each of these features is graded independently, resulting in an overall grade. The outputs can be both values or conditions-based (eBay or TCGPlayer naming). You can test it here.

• We have also been building custom visual search engines for private collections of trading cards and other collectibles. With this feature, people can visit marketplaces or use their apps to upload card images, and effortlessly search for identical or similar items in their database with a click. Visual search is a standard AI-powered function in major price comparators. If a particular game is not on our list, or if you wish to search within your own collection, list, or portfolio of other collectibles (e.g., coins, stamps, or comic books), we can also create it for you – let us know.

We have been gradually establishing a track record of successful projects in the collectibles field. From the feedback of our customers, we hear that our services are much more precise than the competition. So a couple of months ago, we started building a sports card scanning system as well. It allows users to send the scan to the API, and get back precise identification of the card.

Our API is open to all developers, just sign up to Ximilar App, and you can start building your own great product on top of it!

The Main Features of Sports Cards

There are several factors determining the value of the card:

• Rarity & Scarcity: Cards with limited production runs or those featuring star players are often worth more.

• Condition: Like any collectible item, the condition of a sports card is crucial. Cards in mint or near-mint condition are generally worth more than those with wear and tear.

• Grade & Grading services: Graded cards (from PSA or Beckett) typically have higher prices in the market.

• The fame of the player: Names of legends like Michael Jordan or Shohei Ohtani instantly add value to the trading cards in your collection.

• Autographs, memorabilia, and other features, that add to the card’s rarity.

Each card manufacturer must have legal rights and licensing agreements with the sports league, teams, or athletes. Right now, there are several main producers:

• Panini – This Italian company is the largest player in the market in terms of licensing agreements and number of releases.

• Topps – Topps is an American company with a long history. They are now releasing cards from Baseball, Basketball or MMA.

• Upper Deck – Upper Deck is a company with an exclusive license for hockey cards from the NHL.

• Futera – Futera focuses mostly on soccer cards.

Dozens of other card manufacturers were acquired by these few players. They add their brands or names as special sets in their releases. For example, the Fleer company was acquired by Upper Deck in 2005 and Donruss was bought by Panini.

Identifying Sports Cards With Artificial Intelligence

When it comes to sports cards, it’s crucial to recognize that the identification challenge is more complex than that of Pokémon or Magic The Gathering cards. While these games present challenges such as identical trading card artworks in multiple sets or different language variants, sports cards pose distinct difficulties in recognition and identification, such as:

• Amount of data/cards – The companies add a lot of new cards into their portfolio each year. As of the latest date, the total figure exceeds tens of millions of cards.

• Parallels, variations, and colours – The card can have multiple variants with different colours, borders, various foil effects, patterns, or even materials. More can be read in a great article by getcardbase.com. Look at the following example of the NBA’s LeBron James card, and some of its variants.

• Special cards: Short Print (SP) and Super Short Print (SSP) cards are intentionally produced in smaller quantities than the rest of the particular set. The most common special cards are Rookie cards (RC) that feature a player in their rookie season and that is why they hold sentimental and historical value.

• Serial numbered cards: A type of trading cards that have a unique serial number printed directly on the card itself.

• Authentic signature/autograph: These are usually official signature cards, signed by players. To examine the authenticity of the signature, and thus ensure the card’s value, reputable trading card companies may employ card authentication processes.

• Memorabilia: In the context of trading cards, memorabilia cards are special cards that feature a piece of an athlete’s equipment, such as a patch from a uniform, shoe, or bat. Sports memorabilia are typically more valuable because of their rarity. These cards are also called relic cards.

As you can see, it’s not easy to identify the card and its price and to keep track of all its different variants.

Example: Panini Prizm Football Cards

Take for example the 2022 Panini Prizm Football Cards and the parallel cards. Gold Prizms (10 cards) are worth much more than the Orange Prizms (with 250 cards) because of their scarcity. Upon the release of a card set, the accompanying checklist, presented as a population table, is typically made available. This provides detailed information about the count for each variation.

Next, for Panini Prizm, there are more than 20 parallel foil patterns like Speckle, Hyper, Diamond, Fast Break/Disco/No Huddle, Flash, Mozaic, Mojo, Pulsar, Shimmer, etc. with all possible combinations of colours such as green, blue, pink, purple, gold, and so on.

These combinations matter because some of them are more rare than others. There are also different names for the foil cards between companies. Topps has chrome Speckle patterns which are almost identical to the Panini Prizm Sparkle pattern.

Lastly, no database contains each picture for every card in the world. This makes visual search extremely hard for cards that have no picture on the internet.

Luckily, we developed (and are actively improving) an AI service that is trying to tackle the mentioned problems with sports cards identification. This service is available on click as an open REST API, so anyone can connect to develop and integrate their system with ours. The results are in seconds and it’s one of the fastest services available in the market.

How to Identify Sports Cards Via API?

In general, you can use and connect to the REST API with any programming language like Python or Javascript. Our developer’s documentation will serve you as a guide with many helpful instructions and tips.

To access our API, sign in Ximilar App to get your unique API authentication token. You will find the administration of your services under Collectibles Recognition. Here is an example REST Request via curl:

$ curl https://api.ximilar.com/collectibles/v2/sport_id -H "Content-Type: application/json" -H "Authorization: Token __API_TOKEN__" -d '{
    "records": [
        { "_url": "__PATH_TO_IMAGE_URL__"}
    ], "slab_id": false
}'

The API response will be as follows:

• When the system succesfuly indetifies the card, it will return you full identification. You will get a list of features such as the name of the player/person, the name of the set, card number, company, team and features like foil, autograph, colour and more. It is also able to generate URL links for eBay searches so you can check the card values or purchase them directly.
• If we are not sure about the identification (or we don’t have a specific card in our system) the system will return empty search results. In such case, feel free to ask for support.

How AI Sports Cards Identification Works?

Our identification system uses advanced machine learning models with smart algorithms for post-processing. The system is a complex flow of models that incorporates visual search. We trained the system on a large amount of data, curated by our own annotation team.

First, we identify the location of the card in your photo. Second, we do multiple AI analyses of the card to identify whether it has autograph and more. The third step is to find the card in our collection with visual search (reverse image search). Lastly, we use AI to rerank the results to make them as precise as possible.

What Sports Cards Can Ximilar Identify?

Our sports cards database contains a few million cards. Of course, this is just a small subset of all collectible cards that were produced. Right now we focus on 6 main domains: Baseball cards, Football cards, Basketball cards, Hockey cards, Soccer and MMA, and the list expands based on demand. We continually add more data and improve the system.

We try to track and include new releases every month. If you see that we are missing some cards and you have the collection, let us know. We can agree on adding them to training data and giving you a discount on API requests. Since we want to build the most accurate system for card identification in the world, we are always looking for ways to gather more cards and improve the software’s accuracy.

Who Will Benefit From AI-Powered Sports Cards Identifier?

Access to our REST API can improve your position in the market especially if:

• You own e-commerce sites/marketplaces that buy & sell cards – If you have your own shop, site or market for people who collect cards, this solution can boost your traffic and sales.

• You are planning to design and publish your own collector app and need an all-in-one API for the recognition and grading of cards.

• You want to manage, organize and add data to your own card collection.

Is My Data Safe?

Yes. First of all, we don’t save the analysed images. We don’t even have so much storage capacity to store each analysed image, photo, scan and screen you add to your collection. Once our system processes an image, it removes it from the memory. Also, GDPR applies to all photos that enter our system. Read more in our FAQs.

How Fast is the System, Can I Connect it to a Scanner?

The system can identify one card scan in one second. You can connect it to any card scanner available in the market. The scanning outputs the cards into the folders, to which you can apply a script for card identification.

Sports Cards Recognition Apps You Can Build With Our API

Here are a few ideas for apps that you can build with our Sport Card Identifier and REST API:

• Automatic card scanning system – create a simple script that will be connected to our API and your scanners like Fujitsu fi-8170. The system will be able to document your cards with incredible speed. Several of our customers are already organizing their collections of TCGs (like Magic The Gathering or Pokémon) and adding new cards on the go.

• Price checking app or portfolio analysis – create your phone app alternative to Ludex or CollX. Start documenting the cards by taking pictures and grading your trading card collection. Our system can provide card IDs, pre-grade cards, and search them in an online marketplace. Easily connect with other collectors, purchase & sell the cards. Test our system’s ability to provide URLs to marketplaces here.

• Analysing eBay submission – would you like to know what your card’s worth and how many are currently available in the market? For how much was the card sold in the past? Track the price of the card over time? Or what is the card population? With our technology, you can build a system that can analyse it.

AI for Trading Cards and Collectors

So this is our latest narrow AI service for the collector community. It is quite easy to integrate it into any system. You can use it for automatic documentation of your collection or simply to list your cards on online markets.

For more information, contact us via chat or contact page, and we can schedule a call with you and talk about the technical and business details. If you want to go straight and implement it, take look at our developer’s API documentation and don’t hesitate to ask for guidance anytime.

Right now we are also working on Comics identification (Comic book, magazines and manga). If you would like to hear more then just contact us via email or chat.

The post How to Identify Sports Cards With AI appeared first on Ximilar: Visual AI for Business.

Today we are releasing three public API endpoints for evaluating card grade, centering and card condition with AI:

• Card Grading – the most complex endpoint that evaluates corners, edges, surface and centering
• Card Centering – computing just the centering of the card
• Card Condition – simple API for getting condition of the card for marketplace (ebay) submission

In this blog post, I would like to get more in-depth about the AI card grading solution. How we built it, what are the pros and cons, how it is different from PSA grading or Beckett grading services, and how you can use it via REST API for your website or app.

AI Card Grading Services as API

With the latest advances in artificial intelligence, it is becoming increasingly common in our daily lives, and collectible cards are a field that doesn’t get left behind. A lot of startups are developing their own card grading, identification, scanning and documenting systems. Some of them were already successfully sold to big players like eBay or PSA. Just to mention a few:

• CollX raises $5.5M to scan and evaluate the value of trading cards

• eBay acquires several startups from the collectors industry like TCGplayer and 3PM Shield LLC

• Collectible card trading platform Alt raises $75M

• PSA Acquires Genamint to introduce Next-Generation Grading process

• AI trading card startup Ludex raises $8M

To understand why card grading is so popular, let’s look at the standard grading process and how the industry works.

Standard Grading Process

Card grading has gained widespread popularity in the world of collectibles by offering a trusted way to assess trading cards to collectors. It’s a method that gives a fair and unbiased evaluation of a card’s condition, ensuring its authenticity and value. This appeals to both seasoned collectors who want to preserve their cards’ worth and newcomers looking to navigate the collectible market confidently.

The process involves sending cards to experts who carefully inspect them for qualities like centering, corners, edges, and surface. The standard grading process for trading cards involves these key steps:

1. Submission: Collectors send their cards to grading companies.

2. Authentication: Cards are checked for authenticity.

3. Grading: Cards are assessed for condition and assigned a grade from 1 to 10 on a grading scale by an expert.

4. Encapsulation: Graded cards are sealed in protective holders.

5. Labelling & Certification: Labels with card details and grades are added. Cards’ information is recorded for verification. Special labels (such as fugitive ink, QR codes, or serial numbers) are introduced to prevent tampering.

6. Return/Sale: Graded cards are returned to owners or sold for higher value.

Costs of Grading Services

The price for submitting cards and their grading depends on the company and the card. For example, the minimal grading price per card by PSA (Professional Sports Authenticator) is 15 USD, and it’s much more for more expensive cards.

You can pay hundreds of dollars if you have some rare baseball card from Topps or non-sports cards from Magic The Gathering or Yu-Gi-Oh! If your modern card collection contains hundreds of cards, the pricing can reach astronomical values. Of course, grading often makes the card’s value higher, depending on its condition and grade.

Pros And Cons of Classic Grading

Besides its costliness, classic grading has several other drawbacks:

• It is a time-consuming offline process that is not particularly ideal for large-scale grading of whole collections.
• Some grading companies would only grade cards with minimum submission value (declared value that is used for insurance).
• Also, customers can usually submit only cards from popular series such as Pokémon, Magic The Gathering, Yu-Gi-Oh!, Sport Topps cards, and Sport Panini cards.

Of course, there are also advantages – like a physically sealed slab with a graded card, confirming its authenticity, and grading done by experts who can look at a card from all different angles and not just from a single image.

Nevertheless, there are a lot of steps involved in card grading, and the entire process takes a lot of time and effort. AI grading can help with the entire workflow, from authentication to grading and labelling.

Computer vision can easily and consistently spot printing defects, analyze corners and edges individually and compute centering in a matter of seconds and for a fraction of the price.

Introducing Online AI Card Grading REST API Service

Fast & Affordable AI Card Grading

Our intention is by no means to replace expert grading companies like PSA, BGS, SGC or CGC with AI-powered card grading. We would rather like it to be a faster, more consistent & cheaper alternative for anyone who needs bulk pre-grading of their collections.

One use case for our AI grading service is to use it to automate the estimation of the declared value of the card. A declared value is the estimated value of the collectible card after PSA has graded it (read PSA’s explanation here).

First, you will submit your card for grading by just sending the photo to our API. After obtaining a grade from our service, you can use our visual search system or card ID for a price guide. Actually, you will not only get the final grade of the card but a detailed grading breakdown (for edges, corners, centering, and surface). Then you can decide by yourself if you want to spend more money for physical grading or to sell it on eBay.

How Do We Train AI to Grade Cards?

To build an AI grading system powered by computer vision and machine learning techniques, we needed a lot of data that imitated real-world use cases (usually user-generated content such as smartphone pictures).

We spent a lot of time building our own dataset, including damaging our own cards. Our purpose from the beginning was to have a grader that would work both on sports cards and trading card games (TCGs), as well as images of different qualities and with different positioning of the cards.

AI Card Grader Consists of Several AI Models

Our card grading solution integrates a number of machine learning models trained on specific datasets. After you upload a photo of a card, the system needs to be able to correctly detect its position. It then identifies the type of the card: a sports card or a trading card game. Another recognition model identifies whether the picture shows the front or back of the card.

After localization & simple identification, the card gets an individual evaluation of its parts. We trained numerous models for individual grading of corners, edges, card surface, and centering, in accordance with grading standards such as PSA or Beckett.

Of course, different types of cards require a different approach, which is why, for example, we have two different models for corners. While sports cards should have sharp corners, TCG cards are typically more rounded.

From the individual grades, we compute a final grade with condition evaluation. Another model is identifying autographed cards. The cards with autographs are generally more valuable.

The big advantage is that the output of the card grading is easy to visualize. That is why we also provide a simple image with the report for each graded card. There you can see a detailed grading breakdown for every part of the card.

Limitations of AI and Machine Learning in Card Grading

Of course, both humans and AI can make mistakes. There are some limitations of the system. Estimating card grades from the images requires relatively high-resolution images, with good lighting conditions and with low post-processing.

As a matter of fact, a lot of modern cameras in smartphones are currently not very good at close-up photos. Their sensors have gotten bigger over the years, and their AI is upscaling the photos. This makes them artificially sharp with cartoon-like effects. This can of course corrupt the overall results. However, as I previously mentioned, that is why we train the models on real-life images and gradually improve their performance.

Let’s Get Some Cards Graded Via Our Online API

Modern Basketball Card

We can test our AI grader via Ximilar App. For this purpose, I chose one of the classic basketball cards of Michael Jordan. BGS (Beckett) gave this card a grade of 6 (EX-MT).

Our online grading system assigned this card a final grade of 6.5. The centering is quite off, so the system graded it 6/10. The grading is still not perfect, as it misses the surface by quite a large margin. However, the final grade is quite close to the one received by Beckett.

In the breakdown image, you can see how the system evaluated individual parts of the card. The lines are drawn on the image, so you can see the details of individual grades for corners and edges. We hope that this brings more transparency to the algorithmic grading.

Vintage Baseball Card

Now let’s take a look at an image of a vintage sports card without an autograph. As an example, I chose the baseball card with Ed Mathews.

The final grade that the card receives is 6.0. The average corner value assigned by the system is 4.0 and edges are 7.0. The grade for the surface is 5.5 and the centering is 7.0 (left/right is 36/65 and top/bottom is 38/62).

We can take a look at the corners and think whether a professional grader would assign the same values. I personally think that the grade is reasonable. However, getting grades from a single image is hard. We’re also not trying to make the values precise up to decimals (e.g., 4.12453 for the upper left corner). We want this to be an affordable soft pre-grading solution.

Card corners are a bit blurry, so ideally, we would like to have a sharper image. However, we can see that the corners are not in the range of 7–10 grades but rather lower (4-6).

How Do We Compute the Final Grade?

We compute the final grade for corners and edges simply as an average of the individual values. We trained the centering grader according to the Beckett grading scale. It is in our opinion much better (has higher demands) than PSA in this case. So to get 10 points for centering, you need to have a 50/50 ratio – on top/bottom and left/right.

The good thing is, that since we provide values for all parts of the card, you don’t need to use our final grades. You can actually create and use your own formula for computing the final grade.

Card Centering API with AI

Some of our customers would like to compute just the centering of the card. That is why we publish also endpoint for this. It will return you offsets from left, right and top and bottom borders of the card. The offsets are relative and also absolute so you can visualize it in your application. Each API response contains image with visualized centering as part of the output:

Lightweight Grading, alias Card Condition Assessment

For customers that want to submit cards to online marketplaces and need to know just the condition of the card like Near Mint, Lightly Played, Heavily Played or Damaged we offer an additional endpoint for getting rough condition of your card. Because this endpoint (/v2/condition) is much simpler and also significantly cheaper than our /v2/grade endpoint. It’s great for a massive amount of data and suitable for collector shops all over the world. The API endpoint can be called from your application or we can write your own script that is able to analyze images/cards from Fujitsu scanners (Fujitsu FI-8170). If you also want to have a card identification service, our visual search AI can identify the TCGs like Pokemon, Magic The Gathering or Yugioh! with more than 98% accuracy.

You can ask to return the condition in several different formats like TCGPlayer, Ebay or our own.

The more about /v2/condition endpoint can be found in our documentation.

How You Can Test Ximilar Card Grader?

To test our online card grader API, you will need to log into the Ximilar App, where it is currently available to users of all plans for testing purposes. We are also currently working on a public demo.

The system is not perfect, neither is the real human grader. It will take us some time to develop something that will be near perfect and very stable. But I believe that we are on the right track to make AI-powered solutions in the collectibles industry more accessible and cheaper.

To Sum Up

The AI card grader is just one of many solutions by Ximilar that the collector community can use. Make sure to check out our AI Recognition of Collectibles. It is a universal service for the automated detection and recognition of all kinds of collectible items.

The post AI Card Grading – Automate Sports Cards Pre-Grading appeared first on Ximilar: Visual AI for Business.

However, as the world of trading card games expands, collectors increasingly require a versatile trading card game identifier. This tool should swiftly recognize various collectible cards, irrespective of your private collection or database. We accepted this challenge and built a Trading Card Game Identifier (Card ID). In this article, I will describe how it works, and how you can use it for your own App or website. We will also take a brief look at other additions to our Collectibles Recognition: OCR & grading system for both TCGs and sports.

Trading Card Games Identifier

What is the Card Identifier?

Card Identifier is an AI-powered tool by Ximilar able to recognize trading game cards in any image format and provide you with their attributes, such as the name, exact set, series, codes, number, or year of release. It also provides attributes such as information on whether the card is holo (foil-treated) or what alphabet or language it uses.

This solution is an extension of our core service AI Recognition of Collectibles (which does the basic image recognition of all collectible items) and expands its functionalities by detailed identification of specific trading games.

Card ID works independently of keywords and metadata. As a matter of fact, you can use it to generate keywords. You can save the output in JSON or use it for searching and filtering items on your webpage.

The attributes of cards, such as their name, date of release and set, are also typically used to find the trading card’s average price on marketplaces such as TCGPlayer or eBay. That is why for some cards, we can provide links to these sites right away.

There are several use-cases that you can use our card identifier, here are few of them:

• you can connect your card scanner like Fujitsu (fi-8170) and create an system for documenting & digitalising your card collectors inventory, save thousands of hours with AI analysis
• you can build a smartphone app that is able to identify a card from photo and get average price on ebay or tcgplayer
• you can create your own marketplace website for card reselling & listing. Our technology will help with card identification of incoming submissions.

Because our solutions are powered by computer vision, you can upload photos of as many cards as you want, with or without sleeves, under different lighting and conditions.

Which Games Can the Trading Card Game Identifier Recognize?

Pokémon TCG

The Pokémon Trading Card Game is one of the most popular trading games. Fans of all generations and nationalities have been playing Pokémon TCG ever since its release in 1998. Our identifier recognizes Pokémon cards in both English & Japanese and provides their attributes.

Magic The Gathering

MGT is a highly popular game. As of 2023, over 100 MTG sets have been released, with their numbers continually rising, making it increasingly challenging to keep pace with all the sets and new cards. Our identifier provides all basic information about the Magic The Gathering card in an uploaded photo, and we keep adding new attributes.

Yu-Gi-Oh!

Yu-Gi-Oh! is an iconic trading card game based on an anime series. Since its 1999 release, Yu-Gi-Oh! has garnered a dedicated community of players and collectors. Recognized as a top-selling TCG in 2009 by Guinness World Records, with over 22 billion cards sold worldwide, the demand for an AI model to assist with card identification is understandable.

From MetaZoo to Lorcana

TCGs such as MetaZoo TCG, Flesh and Blood TCG, One Piece Card Game, or Lorcana TCG are all smaller or more recent games, but they are starting to be more and more popular both in English-speaking and Asian countries.

Independent of card type, this endpoint will also provide information such as:

• Side – front or back of the card.

• Alphabet – such as Latin, Japanese, Korean, Chinese, and more.

• Holo/Foil – whether the card has a holo effect (aluminium foil).

• Autograph – this particular feature is common rather for baseball and other sports cards.

All this information is necessary to value trading cards properly. For instance, a Japanese card can have a different value than an English one, and a holo card can have a higher value than a regular one.

How Identifying Trading Card Games via API Works?

Connect to API

Once you register in Ximilar App, you will automatically get your own unique API token. You will need at least business pricing plan. Then you can access and use our solutions both via App & API:

• In the App, Card ID is a part of the Collectibles Recognition service. So if you upload your images there, the trading cards in them will be automatically recognized and identified.

• The REST API endpoint is simple to use and easy to integrate into your mobile app, website or card-sorting machines. If you’re new to deploying solutions via API, the API documentation is here to help you with the basic setup. You can also find a lot of helpful information in our Help Center.

• For a lot of cards we are able to provide links to TCG Player or Cardmarket so you will know the price of analysed cards immediatelly.

To access the Card Identifier by Ximilar, use the endpoint /v2/tcg_id:

https://api.ximilar.com/collectibles/v2/tcg_id

We are always here to answer your questions through the contact form or live chat and can also do the setup for you.

Implement Trading Card Game Identifier in Your App

Imagine you are building an app or a site catering to Yu-Gi-Oh! fans and collectors. When a visitor uploads a picture of a new card, our AI Recognition of Collectibles instantly detects the card’s position and confirms it as a trading card. Thanks to its object detection & image recognition capabilities, users can upload pictures containing multiple cards.

Subsequently, the Card ID provides the card’s attributes Name, Full Name, Set, Set Code, Card Number, Rarity and Year. This happens independently of your portfolio (collection) or database.

The identification of the record is fast (usually takes a second to process) and the results are provided in JSON. This way, the user can be provided with structured data on their trading card in a matter of seconds.

The identification works for almost all popular TCGs. And the good news is that our AI for card recognition is so powerful that we can extend it to other games. Let us know if you are missing any games.

New Solutions For Sports Cards

Sports Card Text Analysis With OCR & GPT

Because there are millions of sports cards, and it’s very hard to gather data for them, we have recently released another solution for text extraction from sports cards. The system is accessible via following endpoints:

https://api.ximilar.com/collectibles/v2/card_ocr_id
https://api.ximilar.com/collectibles/v2/sport_id

For the first endpoint. This technology is able to read all the texts in the photo with a card via Optical Character Recognition (OCR) and then provide information on the athlete via Large Language model (LLM) – GPT. This model is still in the works, however, it can help you with the automatization and labelling of the cards. If you have your own collection of sport’s cards then we can build you a precise, fast and affordable AI system for sports card identification.

The second endpoint actually uses a limited sports cards database for identification. You can try to play with both of them and choose the solution that works for you. If you have your own database of sports cards we can build a similar system just on your data.

You can read more about this solution in the article When OCR Meets ChatGPT AI in One API.

Read Graded Slab Labels With AI

Sports card grading is gaining popularity not only in the USA but also in Europe and Asia, as collectors recognize the value of their cards. Having rare foiled cards evaluated by esteemed companies like PSA or Beckett may be a good investment.

Online trading has become a prevalent trend, with eBay leading the pack as the go-to marketplace for collectibles. However, searching for the best deal among thousands of results for a specific query, like a “Michael Jordan Graded Card” can be incredibly time-consuming and challenging.

Our endpoint slab_id reads the graded slabs and helps to automate the identification of promising cards:

https://api.ximilar.com/collectibles/v2/slab_id

It will read the slab and return attributes such as grade, name, grade company and certification number. You can use it to automatically find and filter items with certain grades or conditions (8/9/10, near mint, gem mint, and so on).

Pre-Grading of Sports Cards With AI

We also provide an alternative to the slab reader in case the uploaded card doesn’t have a grade yet. It is an AI-powered grader for websites that evaluate & sell sports cards. The system can grade whole cards as well as individual parts like corners, edges, or centering. It is accessible via endpoint grade (precise) or condition (lightweight and fast):

https://api.ximilar.com/card-grader/v2/grade
https://api.ximilar.com/card-grader/v2/condition

Because identifying grades from a single picture cannot fully replace a professional grader, this endpoint serves mainly as a pre-grading solution. As I write this article, it is currently in beta testing. Nonetheless, it has already proven effective in specific scenarios, particularly with high-resolution pictures of sports cards without sleeves or slabs. This feature was highly requested by many of our customers. So we made it accessible to both Business and Professional plan users.

Solving this challenge is no simple task, and it is a long-term project for us. We are working hard both on gathering training data and improving the model architecture. It serves also as a research project, as we encounter a lot of new and not quite standard things and problems. I will write more about this service, technology, and development in a future blog post. So stay tuned!

Automation in Collectibles Industry Makes Sense

Here are a few reasons why I think the trading card industry is growing rapidly, and will use AI-powered automation more in the future:

• According to Business Research Insights, the global collectible card game market was valued at 13 billion USD in 2021. And it is projected to grow by 16% annually.

• In 2022 alone, 10 million sports cards were graded, indicating significant demand for grading services.

• The TCG potential has caught the attention of major corporations including Disney, evident from their release of the Lorcana TCG in 2023.

• Companies like Nintendo earned nearly 43 million USD from card games playing last year.

• Magic The Gathering remains Hasbro’s most profitable business venture.

The post Build Your Own Trading Card Game Identifier With Our API appeared first on Ximilar: Visual AI for Business.

That is why we in Ximilar have recently developed an OCR system, integrated it with ChatGPT and made it available via API. It is one of the first publicly available services combining OCR software and the GPT model, supporting several alphabets and languages. In this article, I will provide an overview of what OCR and ChatGPT are, how they work, and – more importantly – how anyone can benefit from their combination.

What is Optical Character Recognition (OCR)?

OCR (Optical Character Recognition) is a technology that can quickly scan documents or images and extract text data from them. OCR engines are powered by artificial intelligence & machine learning. They use object detection, pattern recognition and feature extraction.

An OCR software can actually read not only printed but also handwritten text in an image or a document and provide you with extracted text information in a file format of your choosing.

How Optical Character Recognition Works?

When an OCR engine is provided with an image, it first detects the position of the text. Then, it uses AI model for reading individual characters to find out what the text in the scanned document says (text recognition).

This way, OCR tools can provide accurate information from virtually any kind of image file or document type. To name a few examples: PDF files containing camera images, scanned documents (e.g., legal documents), old printed documents such as historical newspapers, or even license plates.

Most OCR tools are optimized for specific languages and alphabets. We can tune these tools in many ways. For example, to automate the reading of invoices, receipts, or contracts. They can also specialize in handwritten or printed paper documents.

The basic outputs from OCR tools are usually the extracted texts and their locations in the image. The data extracted with these tools can then serve various purposes, depending on your needs. From uploading the extracted text to simple Word documents to turning the recognized text to speech format for visually impaired users.

OCR programs can also do a layout analysis for transforming text into a table. Or they can integrate natural language processing (NLP) for further text analysis and extraction of named entities (NER). For example, identifying numbers, famous people or locations in the text, like ‘Albert Einstein’ or ‘Eiffel Tower’.

Technologies Related to OCR

You can also meet the term optical word recognition (OWR). This technology is not as widely used as the optical character recognition software. It involves the recognition and extraction of individual words or groups of words from an image.

There is also optical mark recognition (OMR). This technology can detect and interpret marks made on paper or other media. It can work together with OCR technology, for instance, to process and grade tests or surveys.

And last but not least, there is intelligent character recognition (ICR). It is a specific OCR optimised for the extraction of handwritten text from an image. All these advanced methods share some underlying principles.

What are GPT and ChatGPT?

Generative pre-trained transformer (GPT), is an AI text model that is able to generate textual outputs based on input (prompt). GPT models are large language models (LLMs) powered by deep learning and relying on neural networks. They are incredibly powerful tools and can do content creation (e.g., writing paragraphs of blog posts), proofreading and error fixing, explaining concepts & ideas, and much more.

The Impact of ChatGPT

ChatGPT introduced by OpenAI and Microsoft is an extension of the GPT model, which is further optimized for conversations. It has had a great impact on how we search, work with and process data.

GPT models are trained on huge amounts of textual data. So they have better knowledge than an average human being about many topics. In my case, ChatGPT has definitely better English writing & grammar skills than me. Here’s an example of ChatGPT explaining quantum computing:

It is no overstatement to say that the introduction of ChatGPT revolutionized data processing, analysis, search, and retrieval.

How Can OCR & GPT Be Combined For Smart Text Extraction

The combination of OCR with GPT models enables us to use this technology to its full potential. GPT can understand, analyze and edit textual inputs. That is why it is ideal for post-processing of the raw text data extracted from images with OCR technology. You can give the text to the GPT and ask simple questions such as “What are the items on the invoice and what is the invoice price?” and get an answer with the exact structure you need.

This was a very hard problem just a year ago, and a lot of companies were trying to build intelligent document-reading systems, investing millions of dollars in them. The large language models are really game changers and major time savers. It is great that they can be combined with other tools such as OCR and integrated into visual AI systems.

It can help us with many things, including extraction of essential information from images and putting them into text documents or JSON. And in the future, it can revolutionize search engines, and streamline automated text translation or entire workflows of document processing and archiving.

Examples of OCR Software & ChatGPT Working Together

So, now that we can combine computer vision and advanced natural language processing, let’s take a look at how we can use this technology to our advantage.

Reading, Processing and Mining Invoices From PDFs

One of the typical examples of OCR software is reading the data from invoices, receipts, or contracts from image-only PDFs (or other documents). Imagine a part of invoices and receipts your accounting department accepts are physical printed documents. You could scan the document, and instead of opening it in Adobe Acrobat and doing manual data entry (which is still a standard procedure in many accounting departments today), you would let the automated OCR system handle the rest.

Scanned documents can be automatically sent to the API from both computers and mobile phones. The visual AI needs only a few hundred milliseconds to process an image. Then you will get textual data with the desired structure in JSON or another format. You can easily integrate such technology into accounting systems and internal infrastructures to streamline invoice processing, payments or SKU numbers monitoring.

Trading Card Identifying & Reading Powered by AI

In recent years, the collector community for trading cards has grown significantly. This has been accompanied by the emergence of specialized collector websites, comparison platforms, and community forums. And with the increasing number of both cards and their collectors, there has been a parallel demand for automating the recognition and cataloguing collectibles from images.

Ximilar has been developing AI-powered solutions for some of the biggest collector websites on the market. And adding an OCR system was an ideal solution for data extraction from both cards and their graded slabs.

Automatic Recognition of Collectibles

We developed an OCR system that extracts all text characters from both the card and its slab in the image. Then GPT processes these texts and provides structured information. For instance, the name of the player, the card, its grade and name of grading company, or labels from PSA.

Needless to say, we are pretty big fans of collectible cards ourselves. So we’ve been enjoying working on AI not only for sports cards but also for trading card games. We recently developed several solutions tuned specifically for the most popular trading card games such as Pokémon, Magic the Gathering or YuGiOh! and have been adding new features and games constantly. Do you like the idea of trading card recognition automation? See how it works in our public demo.

How Can I Use the OCR & GPT API On My Images or PDFs?

Our OCR software is publicly available via an online REST API. This is how you can use it:

1. Log into Ximilar App

   • Get your free API TOKEN to connect to API – Once you sign up to Ximilar App, you will get a free API token, which allows your authentication. The API documentation is here to help you with the basic setup. You can connect it with any programming language and any platform like iOS or Android. We provide a simple Python SDK for calling the API.

   • You can also try the service directly in the App under Computer Vision Platform.

2. For simple text extraction from your image, call the endpoint read.

   https://api.ximilar.com/ocr/v2/read

3. For text extraction from an image and its post-processing with GPT, use the endpoint read_gpt. To get the results in a deserved structure, you will need to specify the prompt query along with your input images in the API request, and the system will return the results immediately.

   https://api.ximilar.com/ocr/v2/read_gpt

4. The output is JSON with an ‘_ocr’ field. This dictionary contains texts that represent a list of polygons that encapsulate detected words and sentences in images. The full_text field contains all strings concatenated together. The API is returning also the language name (“lang_name”) and language code (“lang”; ISO 639-1). Here is an example:

   {
     "_url": "__URL_PATH_TO_IMAGE__
     "_ocr": {
        "texts": [
          {
             "polygon": [[53.0,76.0],[116.0,76.0],[116.0,94.0],[53.0,94.0]],
             "text": "MICKEY MANTLE",
             "prob": 0.9978849291801453
          },
          ...
        ],
        "full_text": "MICKEY MANTLE 1st Base Yankees",
        "lang_name": "english",
        "lang_code": "en
     }
   }

   Our OCR engine supports several alphabets (Latin, Chinese, Korean, Japanese and Cyrillic) and languages (English, German, Chinese, …).

Integrate the Combination of OCR and ChatGPT In Your System

All our solutions, including the combination of OCR & GPT, are available via API. Therefore, they can be easily integrated into your system, website, app, or infrastructure.

Here are some examples of up-to-date solutions that can easily be built on our platform and automate your workflows:

• Detection, recognition & text extraction system – You can let the users of your website or app upload images of collectibles and get relevant information about them immediately. Once they take an image of the item, our system detects its position (and can mark it with a bounding box). Then, it recognizes their features (e.g., name of the card, collectible coin or comic book), extracts texts with OCR and you will get text data for your website (e.g., in a table format).

• Card grade reading system – If your users upload images of graded cards or other collectibles, our system can detect everything including the grades and labels on the slabs in a matter of milliseconds.

• Comic book recognition & search engine – You can extract all texts from each image of a comic book and automatically match it to your database for cataloguing.

• Giving your collection or database of collectibles order – Imagine you have a website featuring a rich collection of collectible items, getting images from various sources and comparing their prices. The metadata can be quite inconsistent amongst source websites, or be absent in the case of user-generated content. AI can recognize, match, find and extract information from images based purely on computer vision and independent of any kind of metadata.

The post When OCR Meets ChatGPT AI in One API appeared first on Ximilar: Visual AI for Business.

Other people in our office spent their youth playing Magic The Gathering (with beautiful artworks), or collecting sports cards with their favorite athletes. In my country, basketball cards and ice hockey cards were really popular. Cards are still loved, played, collected, and traded by geeks, collectors, and sports fans across the world! Their market is growing, and so is the need for automation of image processing on websites and apps for collectors. Right now, cards can be seen even as a great investment.

Where can you use visual AI for cards?

Trading card games (トレーディングカード) can consist of tens of thousands of cards. In principle, building a basic image classifier based solely on image recognition leads to low precision and is simply not enough for more complicated problems.

However, we are able to build a complex similarity system that can recognize, categorize, and find similar cards by a picture. Once trained properly, it can deal with enormous databases of images it never encountered before. With this system, you can find all the information, such as the year of release, card title, exact value, card set, or whether it already is in someone’s collection, with just a smartphone image of the card.

Tip: Check out our Computer Vision Platform to learn about how basic image recognition systems work. If you are not sure how to develop your card search system, just contact us and we will help you.

Collectibles are a big business and some cards are really expensive nowadays. Who knows, maybe you have the card of Charizard or Kobe Bryant hidden in your old box in the attic. We can develop a system for you that can automatically analyze the bulk of trading cards sent from your customers or integrate it into your mobile/smartphone app.

What can visual search do for the trading cards market?

In the last year, we have been building a universal system able to train visual models with numerous applications in image search engines. We already offer visual search services for photo search. But, they are optimized mostly for general and fashion images. This system can be tuned to trading cards, coins, furniture & home decor, arts, and real estate, … there are infinite use cases.

In the last decades, we have all witnessed the growth of the TCG community. However, technologies based on artificial intelligence have not yet been used in this market. Plus, even though the first system for scanning trading cards was released by ebay.com, it was not made available for small shops as an API. And since trading card games and visual AI are a perfect match, we are going to change it – with a card image search.

Tip: Check out Visual Product Search to learn more about visual search applications.

Which TCG cards could visual AI help with?

An image search engine is a great approach when the number of classes for the image classification is high (above 1,000+). With TCGs, each card represents a unique class. A convolutional neural network (CNN) trained as a classifier can have poor results when working with a larger number of classes.

Pokémon TCG contains more than 10,000 cards (classes), Magic the Gathering (MTG) over 50.000, and the same goes for basketball or any other sports cards. So basically, we can build a visual search system for both:

• Trading card games (Magic the Gathering, Lord of the Rings, Pokémon, Yu-Gi-Oh!, One Piece, Warhammer, and so on)
• Collectible sports cards (like Ice Hockey, Football, Soccer, Baseball, Basketball, UFC, and more)

A visual search/recognition technology is starting to be used on E-bay when listing trading and sports cards for sale. However, this is only available in the e-bay app on smartphones. The app has a built-in scanning tool for cards and can find the average price with additional info.

Our service for card image search can be integrated into your website or application. And you can simply connect via API through a smartphone, computer, or sorting machine to find exact cards by photo, saving a lot of time and improving the user experience!

Our Pokémon Card Image Search

We’ve been recently training an AI (neural network) model for Pokémon trading cards, Yugioh! and Magic The Gathering. Why these? Pokémon is the most played TCG in the world, the game has simple rules and an enormous fan base. Very popular are also MTG and Yugioh! Some cards are really expensive, but more importantly, they are traded heavily!

With this model, we built a reverse search for finding the exact Pokémon card, MTG and Yugioh! cards, which achieved 94%+ accuracy (i.e. exact image match). And we are still talking about a prototype in beta version that can be improved to almost 100 %. This search system can return you the edition of the card, language, name of the card, year of release and much more.

If you would like to try the system on these three trading card games, then the endpoint for card identification (/v2/tcg_id) from the Collectibles Recognition service is the right choice for you. If you need to tune it on your image collections or have any other games or cards (sports) then just contact us and we can build a similar service for you.

Automatic grading and inspection of cards with AI

A lot of companies are grading sports & trading cards manually. Our visual AI can be trained to detect corner types, scratches, surface wear, light staining, creases, focus, and borders. The Image recognition models are able to identify marks, wrong cut, lopsided centering, print defects and other special attributes.

For example, PSA is a company that has developed its own grading standards for automatic card grading (MINT). With our platform and team, you can automatize the entire workflow of grading with just one photo. We provide several solutions for computing card grades and card condition.

Customized solution for visual search

With the new custom similarity service, we are able to create a custom solution for trading card image search in a matter of weeks. The process for developing it is quite simple:

1. We will schedule a call and talk about your goals. We will agree on how we will obtain the training data that are necessary to train your custom machine-learning model for the search engine.
2. Our machine-learning specialists will assemble a testable image search collection and train a custom machine-learning model for you in a matter of weeks.
3. After meeting all the requirements of PoC, we will deploy the system to production, and you can connect to it via Rest API.

Image Recognition of Collectibles

Machine learning models bring endless possibilities not only to pop culture geeks and collectors, but to all fields and industries. From personalized recommendations in custom fashion search engines to automatic detection of slight differences in surface materials, the visual AI gets better and smarter every day, making routine tasks a matter of milliseconds. That is one of the reasons why it is an unlimited resource of curiosity, challenges, and joy for us, including being geeks – professionally :).

Ximilar is currently releasing on a ready-to-use computer vision service able to recognize collectibles such as TCG cards, coins, banknotes or post stamps, detect their features and categorize them. Let us know if you’d like to implement it on your website!

If you are interested in a customized AI solution for collector items write us an email and we will get back to you as soon as possible. If you would like to identify cards with our Collectibles Recognition service just sign up via app.ximilar.com.

When Visual Content Matters

About 90 % of information transmitted to the human brain is visual. There is no doubt that humans are fixated on visual information, with images and videos being the most popular content on the internet. According to Internet Live Stats, every second, more than 1 000 pictures are uploaded to Instagram and almost 100k videos are played on YouTube.

The more people love using and consuming visual content online, the more important visual merchandising gets. It is clear that if you want to increase the traffic and conversions on your website, you need to make your site and content as visually appealing as possible.

How Does Image Upscaling Work?

Image upscaling, or image enhancement, is a process in which images are enriched with more pixels to get a higher resolution. During this process, the image is divided into segments which are upscaled separately and then put back together. So, for example, during the 4x upscaling, the 64 x 64px segments turn into 256 x 256px.

The pixel multiplication is enabled by AI, using the techniques of deep learning and computer vision. During the training, the neural network learns how to divide each pixel into multiple pixels based on its surroundings. Some image enhancing techniques also involve generative modelling, which generates new information to make the modified image look convincing.

A Few Image Upscaling Examples

Super-resolution upscaling makes the edges and colour transitions smoother. When you find a perfect stock photo, you can increase the resolution by adding 2x, 4x, or 8x more pixels to the image.

Sometimes, the smallest changes to the image make the biggest difference. The upscaled images provide the feeling of greater depth and more details, and leave a better impression.

Where is The Image Enhancement the Most Needed?

Stock Photo Databases

The competition in the stock image market is enormous. Nowadays, users of paid stock photo databases expect combined visual search & search by tags, advanced filtering, high-quality photos, or even an editing interface.

When you implement an upscaling solution, you can level up your customer experience, ensure that images coming from thousands of authors will maintain a certain quality, or even make it a part of your own image editor.

Real Estate Photos

Real estate properties with great image galleries have a significantly greater chance of catching the attention of visitors and finding buyers faster.

If you have a collection of real estate images, you can use Custom Image Recognition to automatically choose the best pictures to be displayed, and then use the Image Upscaler to increase the resolution of images. To do so, you will need to train your categorization task first and then combine it with Image Upscaler via Flows.

E-Commerce

Online sellers usually receive their product pictures from various sources. That is why upscaler is a useful visual merchandising and product page optimization tool. You can add the image enhancement into your automatic image processing system to get a unified resolution for the product listing as well as the highest quality images for the product page.

This can also be done with Flows: you can create a task, which will choose all low-quality images and send them to an upscaling task. You can also combine this service with background removal or add it into a more complex Flow with tagging tasks.

Gaming

Upscaling technology is getting used in more and more industries, but the first super-resolution AI models were used in the gaming industry. For example, Xbox or your latest Nvidia GPU card can artificially increase the resolution of the game. Using image enhancement in games has several advantages:

• The rendering mechanism is used for creating low-resolution scenes and then a fast AI model is used to improve the resolution
• Older games, that are natively optimized for lower resolution, can be eventually played with improved graphics in a higher resolution

Generated Art

Generated images, artworks, and concept art are becoming increasingly popular with technologies such as Dall-E 2 and Midjourney. We tried our Generative (GAN) model on these photos and the results are amazing! You can get beautiful printable art in 4k or 8k resolution with our AI via API. What a time to be alive!

The Technology Behind Image Upscaler

Ximilar currently provides two image upscaling solutions: the Classic Image Upscaler and GAN Upscaler.

Classic Image Upscaler

The Classic Image Upscaler is based solely on pixel multiplication. It multiplies each pixel in an image 2–8 times to achieve a higher resolution without modifications to the image. The image upscaled by a classic upscaler is as true to the original image as possible. It is ideal if you only need to upscale your images without adding anything new. Typical examples are CCTV footage or images with delicate patterns and details, that should remain unchanged.

Ximilar is using the latest architecture of convolutional neural networks trained on high and low-quality images. The model outperforms the bicubic interpolation used in programs like Photoshop by several times.

Post-Processing Methods

The post-processing API can be used to remove unnecessary artifacts and noise from images (Artifact removal), focus on small details (High fidelity), or significantly smooth the entire image (Ironed out).

Each of these post-processing methods is good for different types of images. For example, smoothing is ideal for vector graphics or designs. Artifact removal is best for real-life images, e.g. family photos. High fidelity can be used in professional graphics.

GAN Image Upscaler

GAN Image Upscaler is a bit more advanced, and in fact, recommended upscaling technology, especially for commercial content. This upscaler analyzes the colors, edges, corners, light and shade in the original image and enhances its resolution by generating new pixels, that are as relevant pixels as possible to make the resulting images natural-looking. It makes stock photos and product images look more appealing.

How to Upscale an Image Using the Image Upscaler?

A lot of smartphone apps use upscaling models to improve user photos. Brands such as iPhone or Huawei include enhancing models in their software. These models are hidden from the eyes of the user and participate in making photos. Our super-resolution model can be used anywhere simply by calling the Rest API.

Synchronous and Asynchronous API Requests

A basic upscaling task uses synchronous request, meaning you upload an image, wait for it to be processed and eventually get the upscaled result. Synchronous API requests are typically used in public upscaling tools and are currently set for testing purposes in our App. They can however be ineffective for companies that upscale large volumes of data at once and want to keep track of the progress.

That is why we also provide and recommend an API endpoint for asynchronous requests. The difference is that you send multiple upscaling requests (specified by id), they are queued and then processed one by one. You can also send other requests to track the progress of the job. We especially recommend this approach if you need to upscale whole databases, e.g. e-shops with large product photo collections or stock photo databases. You can also use Webhook and get a notification once the job is done.

The model is accessible via the following async API endpoints:

https://api.ximilar.com/account/v2/request

You can also test upscaling of images in Ximilar App (with the option to use the latest GAN model).

Image Upscaler at Stockphotos.com

The Image Upscaler by Ximilar is used at one of the best-known stock photo banks, StockPhotos. The service is free of charge for testing purposes.

The technology behind image similarity is robust, reliable & fast. Built on state-of-the-art (SOTA) AI models and vector databases, you can search millions of images/products in milliseconds. It is used by big e-commerce players as well as small startups for showing visual alternatives or finding products with pictures. Some of our customers have hundreds of millions of images in their collections and do more than 100 million requests per month. Let’s dive into building a superfast similarity search service for your web.

What is Image Similarity?

Image Similarity, or image similarity search, is a visual AI service comparing, grouping, and recommending visually similar images. For example, a typical use case is a product recommendation of similar items in e-shops. It can also be used for reverse image search, where the query is an external image and the results are images from the collection. This approach gives way more accurate results than searching by tags, labels and other attributes.

Ximilar is using state-of-the-art deep learning models for all visual search services. We build our own indexing & searching technology that can run both as a service or on your hardware if needed. The collections can be focused either on product photos, fashion, image matching, or generic photos (stock images).

Features of the Image Similarity Service

Here are several features of the Image Similarity service that we think are crucial:

• Simple access through the Ximilar App (creating a collection on click) and connection to REST API
• The scalable search service can handle collections with hundreds of millions of similar items (images, videos, etc.) and hundreds of requests per second with both CRUD operations and searching
• The ultra-fast and reliable engine that is mostly deployed in large e-commerce platforms – the query for finding the most visually similar product is low latency (in milliseconds)
• The service is customizable – the platform enables you to train your own model for visual similarity search
• Advanced filtering that supports JSON meta-data – if you need to restrict the result to a specific field
• Grouping based on similarity – our search technology can group photos of the same product as one item
• Security and privacy of your data – only meta-data and the visual representation of the images are stored, therefore your images are not stored anywhere
• The service is affordable and cost-effective both for startups and enterprises, offering free plan for tests as well as discounts with your growth over time
• We can deploy it on your hardware, independently of our infrastructure, and also offline – custom similarity model and deployment appropriate to your needs
• Our search engine and machine learning models improve constantly – maintaining much higher quality than any other open-source project & we are able to build custom search engines with trained models

Applications Using Visual Similarity

According to this research by Deloitte, merchandising with artificial intelligence is more and more relevant, and recommendation engines play a vital part in it. Here are a few use cases for visual similarity engines:

• E-shops that use product similarity to help customers to browse and find related products (e.g. in fashion & luxury items, home decor & furniture, art, wall art, prints & posters, collectible trading cards, comics, trademarks, etc.)
• Stock photo databases suggesting similar content – getting visual alternatives of photos, designs, product images, and videos
• Finding the exact products – apps like Vivino for finding wine or any kind of product are easy to develop for us
• Visual similarity duplicate finder (also image matching or deduplication), to know which images are already in your database, or which product photos you can merge together
• Reverse image search – finding a product or an image with a picture online
• Finding similar real estate based for example on interior design, furniture, garden, etc.
• Comparing two images for similarity – for example patterns or designs

Recommending products to your customers has several advantages. Firstly, it creates a better user experience and helps your customers find the right products faster. Secondly, it instantly makes the purchase rate on your web higher. This means a win on both sides – satisfied customers and higher revenue for you. Read more about customer experience and product recommendations in our blog post on fashion search.

Step by step: Building Real-Estate Image Search

Creating the Collection

So let’s take a look at how to easily build your own similarity search engine with the Ximilar platform. The first step is to log in to the Ximilar App. If you don’t have an account, then sign up – it’s free and takes just a minute. After that, on the Dashboard, click on the Visual Search tile and then the Image Similarity service. Then go to the Collections in the left menu and click on Create New Collection. It will show a pop-up with different collection types from which you need to select one.

The collection is a space where you upload your images. With this collection, you are performing queries for search. You can choose from Generic Photo Collection, Product Photo Collection, Dominant Colors Similarity, and Image Matching. Clicking on one of the cards will create a collection for your account.

Each of these collection types is suitable for different types of images:

• Use Generic Photos if you work with stock photos
• Pick a Product Photos collection if you are an e-commerce company
• Select Image Matching to find duplicates in your images
• For the fashion sector, we recommend using a specialized service called Fashion Search
• Custom Similarity is suitable if you are working with another type of data (e.g. videos or 3D models). To do this, please schedule a call with us, and we will develop your own model tuned for your data. For instance, we built a photo search system for the Magic the Gathering Trading Cards for one of our customers.

For this example of real estate, I will use a Generic Photo Collection. The advantage of Generic Photo Collection is that it also supports searching images via text input/query. We usually develop custom similarity models for real estate, when the customers need specific and more accurate results. However, for this simple use case, the generic real estate model will be enough.

Format of Image Similarity Dataset

First, we need to prepare a text file with JSON records. Each record represents an image that we want to store/insert into our collection. The key field is "_url" with the image URL. The advantage of the _url is that you can directly see and inspect the results via app.ximilar.com.

You can also optionally send records with base64 data, this is great if your data are stored locally on your computer. Don’t worry, we are not storing the whole images (data or base64) in the collection database, just URLs with all other metadata present in the records.

The JSON records look like this:

{"_id": "1_1", "_url": "_URL_IMAGE_PATH_", "estate_id": "1", "category": "indoor", "subcategory": "kitchen", "tags": []}
{"_id": "1_2", "_url": "_URL_IMAGE_PATH_", "estate_id": "1", "category": "indoor", "subcategory": "kitchen", "tags": []}
...

If you don’t have image URLs, you can use either "_file" or "_base64" fields for the image data (locally stored "_file" data are automatically converted by the Python client to base64). The image similarity engine is indexing every record of the collection by extracting a representation from the image by a neural network model. However, we are not storing the images in our engine. So, only records that contain "_url" will be visualized in the Ximilar App.

You must store unique identifiers of each image in the "_id" field to identify your images in the collection. The value of this field must be a string. The API endpoint for searching is returning this _id values, that is how you get the results for visual search. You can also store additional fields for every JSON record, and then you can use these fields for filtering, grouping, and tuning the similarity function (see below).

Filling the Collection With Your Data

The next step requires a few lines of code. We are going to insert the prepared images into our collection using our python-client library. You can install the library using pip or directly from GitLab. The usage of the client is very straightforward and basically, you can just use the script tools/collections/insert_json_records.py:

python insert_json_records.py --type generic --auth_token __YOUR_TOKEN__ --collection_id __COLLECTION_ID__ --path /path/to/the/file.json

You will find the collection ID and the Authorization token on the “collection page” in the Ximilar App. This script will run for a few minutes, depending on the size of your image dataset.

Result: Finding Visually Similar Pictures

That was pretty easy, right? Now, if you go to the collections page, you will see something like this:

All images from the JSON file were indexed, and now you can inspect the collection in the Ximilar App. Select the Similarity Search in the left menu of the Image Similarity service and test how the similarity works. You can specify the query image either by upload, by URL, or your IDs, or by choosing one of the randomly selected images from the collection.

Even though we have indexed just several hundred images, you can see that the similarity engine works pretty well. The first image is the query image and the next images are the k-nearest to the query image:

Rest API Connection for Image Search

The next step might be to integrate the service into your application via API. You can either directly use the REST API for searching visually similar images or, if you are using Python, we recommend our Python SDK client like this:

# pip install ximilar-client
from ximilar.client import SimilarityPhotosClient
client = SimilarityPhotosClient("_API_TOKEN_", "_COLLECTION_ID_")
# search k nearest items
client.search({"_id": "1"}, k = 3)
# search by external image

Advanced Features for Photo Similarity

The search for visually similar images can be combined with filtering on metadata. This metadata can be stored in the JSON, as in our example with the "category" and "subcategory" fields. In the API, the filtering is specified using a MongoDB-like syntax – see the documentation.

For example, let’s say that we want to search for images similar to the image with ID=1_1 that are indoor photos made in a kitchen. We assume that this meta-information is stored in the “category” and “subcategory” fields of every JSON record. The query will look like this:

client.search({"_id": "1_1"}, filter={"category": "Indoor", "subcategory": "Kitchen"})

If we know that we will often filter on some fields, we can specify them in the “Fields to index” option of the collection to make the query processing more efficient.

Often, your data contains several photos of one “object” – a product or, in our example, real estate. Our service can group the search results not by individual photos but by product IDs. You can set this in the advanced options of the collection by specifying the name of the real estate in the Product ID field, and the magic will happen.

Enhancing Image Similarity Engine with Tags

The image similarity is based purely on the visual content of the image. However, you can use your tags (labels, keywords) to enhance the similarity search. In the example, we assume that the data already contains categories, subcategories, and tags. In order to enhance the visual similarity search with tags, you can fill the “tags” field for every record with your tags, and also use method /v2/visualTagsKNN. After that, your search results will be based on a combination of visual similarity and keywords.

If you don’t have categories and tags, you can create your own photo tagger through our Image Recognition service, and enrich your image data automatically before indexing. The possibilities of image recognition models and their combinations are endless, resulting in highly customizable solutions. Read our guide on how to build your own Image Recognition API.

You can build several models:

• One classifier for categorizing indoor/outdoor/floor plan photos
• One classifier for getting room type (Bedroom, Kitchen, Living room, etc.)
• One tagger for outdoor tags like (Pool, Garden, Garage, House view, etc.)
