Detailed Description

template<typename 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.

Member Function Documentation

template<typename TSparseImageType >
virtual NodeDataType itk::FiniteDifferenceSparseImageFunction< TSparseImageType >::ComputeSparseUpdate ( NeighborhoodType neighborhood,
void *  globalData,
const FloatOffsetType offset = FloatOffsetType(0.0) 
) const
pure virtual

The update called from the FiniteDifferenceSparseImageFilter. This function replaces the ComputeUpdate function.

Implemented in itk::NormalVectorDiffusionFunction< TSparseImageType >.

template<typename TSparseImageType >
virtual PixelType itk::FiniteDifferenceSparseImageFunction< TSparseImageType >::ComputeUpdate ( const NeighborhoodType ,
void *  ,
const FloatOffsetType  
)
inlineoverridevirtual

This function is not called from the FiniteDifferenceSparseImageFilter class because we need to work with neighborhoods of pointers to data variables instead of neighborhoods of data directly. This function is replaced by the ComputeSparseUpdate function.

Implements itk::FiniteDifferenceFunction< TSparseImageType >.

Definition at line 85 of file itkFiniteDifferenceSparseImageFunction.h.

template<typename TSparseImageType >
virtual const char* itk::FiniteDifferenceSparseImageFunction< TSparseImageType >::GetNameOfClass ( ) const
virtual
template<typename TSparseImageType >
virtual void itk::FiniteDifferenceSparseImageFunction< TSparseImageType >::PrecomputeSparseUpdate ( NeighborhoodType ) const
inlinevirtual

This function provides support for a 2 step update computation that avoids repetitive computation. FiniteDifferenceSparseImageFilter first calls this function for all active pixels in the SparseImage class, then calls ComputeSparseUpdate for the same set of pixels. This is used in NormalVectorDiffusionFunction to calculate flux variables which are then used to compute the updates. Intermediate variables such as the flux in the above examples are stored in the nodes of the SparseImage itself. Therefore, this function will have to know about the NodeType it is dealing with. This function does nothing by default.

Reimplemented in itk::NormalVectorDiffusionFunction< TSparseImageType >.

template<typename TSparseImageType >
void itk::FiniteDifferenceSparseImageFunction< TSparseImageType >::PrintSelf ( std::ostream &  os,
Indent  indent 
) const
overrideprotectedvirtual

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.

Reimplemented from itk::FiniteDifferenceFunction< TSparseImageType >.

Reimplemented in itk::NormalVectorDiffusionFunction< TSparseImageType >, and itk::NormalVectorFunctionBase< TSparseImageType >.
