Detailed Description

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

This class forms the base for any anisotropic diffusion function that operates on scalar data (see itkAnisotropicDiffusionFunction). It provides some common functionality used in classes like CurvatureNDAnisotropicDiffusionFunction and GradientNDAnisotropicDiffusionFunction.

◆ CalculateAverageGradientMagnitudeSquared()

template<typename TImage >

void itk::ScalarAnisotropicDiffusionFunction< TImage >::CalculateAverageGradientMagnitudeSquared ( TImage * )

overridevirtual

This method is called before each iteration. It calculates a scalar value that is the average of the gradient magnitude squared at each pixel in the output image (intermediate solution). The average gradient magnitude value is typically used in the anisotropic diffusion equations to calibrate the conductance term.

Implements itk::AnisotropicDiffusionFunction< TImage >.
