Detailed Description

template<class TImageType>
class itk::GPUFiniteDifferenceFunction< TImageType >

This is a base class of GPU finite difference function. Note that unlike most GPU classes, derived class of GPUFiniteDifferenceFunction does not have corresponding CPU class as its parent but only has CPU class FiniteDifferenceFunction as its base class. Therefore, only members of FiniteDifferenceFunction are reused by its derived GPU classes.

How to use this class
GPUFiniteDifferenceFunction must be subclassed to add functionality for GPUComputeUpdate.

Definition at line 111 of file itkGPUFiniteDifferenceFunction.h.

template<class TImageType>
virtual void itk::GPUFiniteDifferenceFunction< TImageType >::InitializeIteration ( )
inlinevirtual

This method allows the function to set its state before each iteration of the finite difference solver (image filter) that uses it. This is a thread-safe time to manipulate the object's state.

An example of how this can be used: the AnisotropicDiffusionFunction class of FiniteDifferenceFunction use this method to pre-calculate an average gradient magnitude across the entire image region. This value is set in the function object and used by the ComputeUpdate() methods that are called at each pixel as a constant.

Reimplemented from itk::FiniteDifferenceFunction< TImageType >.

Reimplemented in itk::GPUDemonsRegistrationFunction< TFixedImage, TMovingImage, TDeformationField >, and itk::GPUGradientNDAnisotropicDiffusionFunction< TImage >.

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.
