At the moment, I am continuing my work on segmentation algorithms. As I am not the most patient guy, one of the first things I did was write Python bindings for Brian Fulkersons "Really Quick Shift". It's a GPU implementation of the quick shift image segmentation algorithm.
Brian's version has a simple command line interface that loads images.
I wanted to do it a little more direct and used boost python to hand over the memory directly.
You can check it out on github. You'll also find some python bindings for Brian's CPU quickshift within vlfeat there.
