Detailed Description

template<typename TInputImage, typename TOutputImage, typename TParentImageFilter = DenseFiniteDifferenceImageFilter< TInputImage, TOutputImage >>
class itk::GPUDenseFiniteDifferenceImageFilter< TInputImage, TOutputImage, TParentImageFilter >

This is the GPU version of DenseFiniteDifferenceImageFilter class. Currently only single-threaded, single GPU version is implemented. See documentation for FiniteDifferenceImageFilter for an overview of the iterative finite difference algorithm:

: $u_{\mathbf{i}}^{n+1}=u^n_{\mathbf{i}}+\Delta u^n_{\mathbf{i}}\Delta t$

: This class defines an update buffer for $\Delta$ and the methods GPUCalculateChange() and GPUApplyUpdate(), which are GPU version of CalculateChange() and ApplyUpdate().

Use m_UpdateBuffer defined in CPU superclass (DenseFiniteDifferenceImageFilter).

How to use this class: This filter can be used as a base class for GPU implementation of DenseFiniteDifferenceImageFilter.
