Hey Marc. I just saw that you are working on graph cuts and segmentation for skimage. That is pretty awesome. I'm super busy at the moment so I only sort of follow skimage at the time and I can't see melange. Could you shortly give an idea of what the goals of your GSOC are? Are you also planning to implement alpha-expansion? And what are the thoughts about the patent issues? Also, I seem to have completely missed the fact that skimage wants to do gpu now. Are there any pointers on how this is planned / what is already implemented? I implemented some of the segmentation algorithms in skimage and I'd really like to know what is happening and if I could help in any way. I also did some energy minimization stuff, but was a bit bummed out by the patent issues. Btw, the slic implementation is not identical with the reference implementation. If you want to work on segmentation, I think this should really be investigated .... Cheers, Andy
