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 TimeStepType itk::GPUAnisotropicDiffusionFunction< TImage >::ComputeGlobalTimeStep ( void * ) const

inlinevirtual

Returns the time step supplied by the user. We don't need to use the global data supplied since we are returning a fixed value.

const double& itk::GPUAnisotropicDiffusionFunction< TImage >::GetAverageGradientMagnitudeSquared ( ) const

virtual void* itk::GPUAnisotropicDiffusionFunction< TImage >::GetGlobalDataPointer ( ) const

inlinevirtual

The anisotropic diffusion classes don't use this particular parameter so it's safe to return a null value.

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.

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
