/**
 \defgroup ITKAnisotropicSmoothing Module ITKAnisotropicSmoothing 
 This module contains filters that implement variations of
anisotropic smoothing. This is an image denoising technique that strives for
preserving edges on the images while smoothing regions of uniform intensity.
This type of filtering is convenient as a preprocessing stage of segmentation
algorithms. You may find useful as well the filters in
\ref ITKCurvatureFlow and \ref ITKSmoothing.
