Track reference features

[magnus-haw]

Multiple aspects to this- need a user interface to select 0-3 reference features (perhaps even use this to estimate angles?). Need a computer vision algorithm to track features across entire video, and need to integrate the data into the output json files.

I believe this tutorial could be useful. We just need to decide what we want to track. Ideally, we should try to have a hole drilled in the arm for tracking in new videos, or use a distinct spot of color.

I think it needs to be more general in the initial feature identification. Might need to find an edge or a bolt or a corner but shouldn't be limited to a special feature (e.g., use template tracking which periodically updates the template)
