/** \class GradientAnisotropicDiffusionImageFilter
*
* This filter performs anisotropic diffusion on a scalar itk::Image using the
* classic Perona-Malik, gradient magnitude based equation implemented in
* itkGradientNDAnisotropicDiffusionFunction. For detailed information on
* anisotropic diffusion, see itkAnisotropicDiffusionFunction and
* itkGradientNDAnisotropicDiffusionFunction.
*
* \par Inputs and Outputs
* The input to this filter should be a scalar itk::Image of any
* dimensionality. The output image will be a diffused copy of the input.
* \par Parameters
* Please see the description of parameters given in
* itkAnisotropicDiffusionImageFilter.
