Detailed Description

template<class TImage>
class itk::GPUAnisotropicDiffusionFunction< TImage >

This is the GPU version of AnisotropicDiffusionFunction class.

How to use this class: This class must be subclassed to provide the GPUCalculateUpdate() methods of GPUFiniteDifferenceFunction and the function CalculateAverageGradientMagnitudeSquared(), which is called before each iteration to recalibrate the conductance term.

virtual void itk::GPUAnisotropicDiffusionFunction< TImage >::GPUCalculateAverageGradientMagnitudeSquared ( ImageType * )

pure virtual

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.
