Detailed Description

Compute medical skeleton of a (binary) mask image.

Warning:

This operation is not working properly. Due to discretization of the image gradient and Hessian, we fail to detect the exact locations of critical points, which in general do not coincide with grid locations. In other words, even when a discrete pixel is a local maximum, the discrete gradient of the image function does not usually vanish at that point. Inherit generic image operation.
