The current game is one where you play with one another using physical cards in the real world, but our goal was to propose a new way of playing the game: one that could be compatible with computer games in the future.

As of its 20th Anniversary, there are already over 9000 different cards in the the Yugioh Official Card Game.

It would be impossible to apply identification methods such as QR codes to such a large number of cards, so instead, the team looked to image recognition software.

The original system required 20 days of machine learning to process 9000 cards, with only a 50% accuracy rate.

“It wasn’t usable. There was something missing when compared to distinguishing cards with the human eye.”

Thats why they came up with a solution: “semi-transparent composite images”.

Card images are rendered on a computer. Here, two slightly different semi-transparent card images are rendered and then merged together. This new image is then used for the machine learning process.
