Detailed Description

template<class TSparseImageType>
class itk::FiniteDifferenceSparseImageFunction< TSparseImageType >

This is the base class for function classes that can be used with filters derived from FiniteDifferenceSparseImageFilter.

This class is derived from FiniteDifferenceFunction. It is designed to: *work with neighborhoods of pointers instead of actual data. Towards this *purpose ComputeUpdate method is no longer used and is replaced by the *ComputeSparseUpdate method. ComputeSparseUpdate assumes that the pointers are *associated with structures that have the member variable m_Data. The pointers *would normally originate from a SparseImage object.

The PrecomputeSparseUpdate method can be defined to do a first pass of: *computations which then can be used by ComputeSparseUpdate. If *PrecomputeSparseUpdate is used then the m_PrecomputeFlag should be set in the *FiniteDifferenceSparseImageFilter class. The precomputation step can be used *to speed up computation by avoiding repetitions. See the *NormalVectorDiffusionFunction for an example.
