Optical flow hand & body segmentation

Hey Lab members

Recently bought the Flow kit and I am struggling to achieve optical flow for hand and body segmentation.

Not sure if I can get a guide to get this right, but any help would be great.

Please see media for what I wanna do

Can you show some of what you’ve tried so far? My first thought is to use the segmented body texture in the optical flow patch. I don’t remember offhand if OF does anything with the alpha channel, but you could try putting it on a black or white matte.
