Functions

VImage VNonmaxSuppression (VImage dx, VImage dy, VImage dz, VImage dest)

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.
