Part 3 of the CollectorVision series. Part 1 has the overview. After Cornelius finds the card and the perspective is corrected, you have a clean 252 × 352 crop. The next problem is figuring out which of 108,000 cards it is. --- Why not a classifier? The obvious approach is to…

I've been working on a card scanner for Magic: The Gathering for a while now and wanted to write up how it works. The short version: you show it a card, it tells you what it is. It handles held cards, sleeved cards, skewed angles, phone cameras. The whole thing runs locally —…

This new algorithm felt cute. Might delete later. Part 2! Playing around with neural networks and some new scanning algorithms. Had several people ask me about the framerate in the previous video, so decided to post a followup where I'm running at 10fps. This is being served by…
