/**
 \defgroup ITKImageFeature Module ITKImageFeature 
 This module contains classes that compute image features. In
particular you will find here: Canny edge detection, Sobel, ZeroCrossings,
Hough transform for lines and circles, Hessian filters, Vesselness, and
Fractional anisotropy for tensor images.
