It's pretty easy with convolutional neural networks (CNNs). You use them to detect where the borders end and begin (called edge detection) on each side and then count the pixels between the edges. But it's clear from the results that it's not doing that, so that's why I suggested that it's doing the typical ChatGPT LLM approach and simply bluffing because most cards are in fact OC.
