Although this is a unique talk, most of the current resources I found during research for the task itself and they all use Python. I’d rather use Elixir! I encountered the problem while building a web app for practicing chess tactics. I wanted to use the images in tactics books without manually setting up the digital board for each of the hundreds of exercises per book. Wouldn’t it be nice to take a picture of the board (a real-life or an abstract image) and have the app automatically set up the exercise? That would let me load arbitrary exercise books into the system in a fraction of the time.
