video2bvh2.0

https://github.com/Dene33/video_to_bvh but with python 3 and tensorflow2.0

Uses Openpose to crop frames around a single person and then uses hmr2.0 by Russoale to get 3D pose keypoints. Then, using Dene33's fork of hmr, the 3D pose keypoints are converted to bvh.

Input video is Man dancing on rooftop by cottonbro. The bvh on the left is lagging slightly behind the video on the right. Will upload better demo videos later.

To Do:

• [ ] Apply filters to smoothen the wobblyness
• [ ] Add support for multiple videos at once
• [ ] If I get time, Dash inline application.
