Furthermore, the letters are in the same place, which makes it easier to parse images of the game board.

Fortunately, the letters we need to detect are consistent. Getting enough screenshots for good training was going to take some time and there was a challenge in getting enough of the rare letters, like Q or Z, to effectively train the model. The first step was to collect enough images to be able to train a model to detect letters. This approach allowed me to capture images from the show to use for training and grab images to send for inference to detect letters. This project uses a USB HDMI capture device connected to a Roku express to capture images from the show while it is being aired. Computer vision to the rescue! After a few weeks of training and coding, I am excited to share a project that does exactly that.
