Ask HN: Getting started with markerless motion capture

Collective HN Brain,

I want to start a project, but I'd like to see if there's any advice from the people with experience. I could've sworn there was something about this recently non-Kinect related, but I couldn't find it. And finding good information on this seems difficult (or I'm terrible at searching).

I'm looking to do some motion tracking and/or analysis. Where is the best place to start from scratch, today? I did some motion tracking with C + a webcam in college, and it was unpleasant. Is Python + Kinect the way to go? Or is there a more established/efficient path? Or some startup solving this problem?

Doesn't have to be real-time, but real-time is an option.

Thanks.
