I decided to create my own dataset for my use case. 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. The correct ones are visible of course, but there is no way to see the guesses that were incorrect. This post was contributed to the Roboflow blog by Warren Wiens, a marketing strategist with 20+ years experience in technology who is learning about AI in their spare time.Īs a regular fan of Wheel of Fortune, I often find myself wishing that I could see all the letters that have been guessed for a puzzle.
