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