Sebastien’s Status Report for 5/1/2021

Over the past two weeks I transitioned all of the existing code to use mediapipe instead of the pipeline I wrote from scratch using boost. Even though mediapipe is written almost entirely in C++, only the python api is documented, so a lot of the work was looking through the source code to figure out what was actually going on and figuring out how to pipe the existing hand pose estimator into our own drawing subsystem. I finally got everything together on tuesday, and since then I’ve added an input stream that reads key-presses so that we can add more drawing modes. When I did that, the pipeline came to a screeching halt. It turns out it was an issue with how mediapipe synchronizes the pipelines it is used to be built. After spelunking in the source again I figured out how to properly synchronize the graph so that problem was fixed. Finally I added a mode for drawing straight lines.
