shrinkWrap

shrinkWrap creates a binary map for automatic segmentation of high intensity areas in a 2D/3D images

This function amplifies areas of high intensity and segments them using a front. The front is initialized on the convex hull (for speed) and erodes the map until it has converged on the edge of the areas to keep, maintaining edge geometry.

The idea and title for this function come from Dr. Tong Zhang's PhD Thesis (RPI, 2004), who used a fast marching level set method and a rapid change in gradient magnitude for the segmentation.
