Cody’s status report for 11/16

After trying another OCR library which ended up also being more inaccurate than I would like, I decided to implement my own character recognition. To do this, I added a small database of characters and I perform nearest-neighbor on each isolated character. This seems to result in high accuracy in the testing I’ve done. I also made the logic for mapping characters onto the board more robust, accounting for if fewer than all 4 corner characters are identified (we still need at least 2). The mapping appears pretty accurate but if a tile is close to the edge, it sometimes gets mapped to the adjacent tile. I will try to improve this as much as I can. For the demo, I plan to show the pipeline of image -> preprocessing -> contour recognition and filtering -> individual classification -> mapping onto board.
