A linear gradient filter
#include "dip_linear.h"
dip_Error dip_SobelGradient ( in, out, boundary, processDim )
binary, integer, float, complex
The SobelGradient filter computes a finite difference gradient (1 0 -1)/2 in the processDim, and performs a local (1 2 1)/4 smoothing in the other dimensions. Note that in 2D, this differs by a multiplication factor of 1/8 to the original definition by Sobel.
