EDGE DETECTION

Hello,

I am Natalia Cantavella and I was reading your code to try to identify how you segmented the edges. I am involved in a project about segmenting the putamen, caudate, and thalamus in Multiple Sclerosis. We have good dice results but our problem is that the edges are not well segmented. I was wondering if you could explain to me how could I do to segment them right.

Thanks for all.

Natalia
