thanks for the contribution and sorry for the slow reply.
Can you add an example that uses this code, as well as documentation and tests?
The reason why I haven't included this in the repo is because pystruct doesn't rely on any segmentation algorithms as it's domain agnostic. It would be better to have this in an image segmentation package, I think. Unfortunately I never got around to write a tutorial or package to do the full pipeline in a clean way.
