This module can be used to perform semi-automatic segmentation by evolving an initial surface in 3D. The method uses a 3D affine invariant edge detector to create potential well where the evolving surface converges. Use fiducials to create initial contours (spheres) inside the object of interest. Use the expand button to inflate the initial contours for several iterations untill it converges to the object boundary. To make the surface smooth, use the smooth button for a few iterations. Technical details about this method can be found in the paper mentioned here.
