Mediapipe

This library from Google can be used to add landmarks to images of people. There are examples of the different things that it can do here.

This is the example from the demo colab

Posemodel Girl

There are 2 things that I might want to do with this:

I am going to try to use this to process my Irish Dancer pictures to find the dancer in them. This is an alternative to labeling in the browser.
Write some software to 'observe' me doing bodyweight exercises. Things like determining if my shoulders are level during pushups.

Before I settled on mediapipe I took a look at some other posemodels. This model from CMU was a bit cumbersome to run on wsl. I don't want to have to compile any C++ on wsl as there is a good chance that it will not work.
