#include <itkMinMaxCurvatureFlowFunction.h>

Detailed Description

template<typename TImage>
class itk::MinMaxCurvatureFlowFunction< TImage >

This class encapsulate the finite difference equation which drives a min/max curvature flow denoising algorithm.

This class uses a zero flux Neumann boundary condition when computing derivatives near the data boundary.

This class operates as part of the finite difference solver hierarchy.
