Detailed Description

NonMaxima Supression by gradient interpolation

This function is used in conjunction with edge detection. The input into this function is the output of a 3D edge detection procedure (e.h. VCanny3d or VDeriche3d). It produces an output image containing the gradient magnitude. Nonmaxima edges are suppressed.
