Detailed Description

This filter performs anisotropic diffusion on a scalar itk::Image using the modified curvature diffusion equation (MCDE).

For detailed information on anisotropic diffusion and the MCDE see itkAnisotropicDiffusionFunction and itkCurvatureNDAnisotropicDiffusionFunction.

Inputs and Outputs

The input and output to this filter must be a scalar itk::Image with numerical pixel types (float or double). A user defined type which correctly defines arithmetic operations with floating point accuracy should also give correct results.

Parameters

Please first read all the documentation found in AnisotropicDiffusionImageFilter and AnisotropicDiffusionFunction . Also see CurvatureNDAnisotropicDiffusionFunction .

The default time step for this filter is set to the maximum theoretically stable value: 0.5 / 2^N, where N is the dimensionality of the image. For a 2D image, this means valid time steps are below 0.1250. For a 3D image, valid time steps are below 0.0625.
