Chessboard won't get recognized correctly

[al-bonin]

Hello, the chessboards won't get recognized correctly or the tiles cannot be created, when I used screenshot. I checked the created tiles, the program detects chessboard wrong for example with the edges or asymmetrical. That's why It cannot recognize the chessboards from screenshots that I cut manually.

Maybe could you upgrade the program? ChessVisionBot from kochsebastian has a good chess recognition function, you can check it for an example.
