==========================================

Group (Subgroup)

ITKImageProcessing (ITKImageProcessing)

Description

Computes the Magnitude of the Gradient of an image by convolution with the first derivative of a Gaussian.

This filter is implemented using the recursive gaussian filters

\par Wiki Examples:

\li All Examples

\li Find the gradient magnitude of the image first smoothed with a Gaussian kernel

Parameters
