itk::NormalVectorFunctionBase< TSparseImageType > Class Template Reference

#include <itkNormalVectorFunctionBase.h>

Detailed Description

template<typename TSparseImageType>
class itk::NormalVectorFunctionBase< TSparseImageType >

This class defines the common functionality for Sparse Image neighborhoods of unit vectors.

This class is derived from the FiniteDifferenceSparseImageFunction class and adds the functionality needed to process unit normal vector neighborhoods.

This class is the parent class of the NormalVectorDiffusionFunction class which defines all the necessary functionality for performing diffusion operations on unit vectors stored in sparse images. Other (non-diffusion) filters (such as median filtering) on unit vectors can also be derived from this base class.

PARAMETERS

This function class has a time step parameter which is returned by the ComputeGlobalTimeStep method. Unlike other finite difference function classes, this class does not use the maximum change magnitude to compute the time step, it returns this predetermined time step.
