morphological_chan_vese

[haesleinhuepf]

Hi @grahamross123 and @StRigaud ,

just to let you know: I made the morphological_chan_vese work. I'm adding a comment below highlighting the little tricky bit. I also renamed the function to be more similar to the scikit-image API.

If you have time, give it a try. I will otherwise merge and release in about a week.

Big thanks again for working on this!

Hint: I had to initialize this image here with 0 because the create* functions only allocate memory. Further down, we compute temp_3 += .... which might be dangerous with a non-initialized image.

Thanks for finishing this @haesleinhuepf! It works as expected for me.
