nickponlineon Shapefit: Turn irregular shape masks into clean polygons

I've encountered this problem many times and tried to solve it with different computer vision and algebra methods. Since it's easy to generate clean polygons and augment them a NN can be trained to undo it.

Ah yes quite right.

I think this problem is called the maximum-weight closure and can be solved as max flow. You want to find a cut between source (horse) so they were no out-going edges not in the cut (escape routes).

Thanks for the kind words. I was actually looking for a better blogging platform as things weren't really discoverable on svbtle and then kind of forgot about it. But I've resumed it this year.

I'd be really interested to know if this can be computed directly any other way?
