General Information
The purpose of this filter is to create a feature image that is suitable for a level-set algorithm, from an intensity image.
It takes the original image and performs anisotropic gaussian diffusion on it, reducing the noise while preserving the edges.
Then the magnitude of the gradient is computed. This magnitude is then non-linearly remapped so as to get very small values in the image edges and very big values in homogeneous areas.
