Detailed Description

template<typename 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.
