Devlog #2

Finished the letter detection for my Wordle bot! After tweaking the contour filtering, the bot now ignores all the extra shapes on the board and only saves the actual letter contours.

I also went down a rabbit hole trying to crop the screenshot to just the Wordle board. I originally thought I’d need a complicated approach, but it turned out the simplest solution was to filter contours by their area and square aspect ratio to isolate the board. I also improved the thresholding so it works reliably in both Wordle’s light and dark themes.

After that, I started experimenting with TensorFlow to identify the color of each tile (green, yellow, and gray). It’s my first time working with TensorFlow, so there’s definitely been a learning curve, but once the model is trained the bot should be able to read Wordle’s feedback automatically.
