Detailed Description

template<class TLevelSet>
class itk::ReinitializeLevelSetImageFilter< TLevelSet >

Reinitialize the level set to the signed distance function.

ReinitializeLevelSetImageFilter reinitializes the input level set to the approximated signed distance function from a particular level set. The output is a level set of the same type as the input.

For some level set algorithms, it is useful to periodically reinitialize the level set function to prevent numerical accuracy problems in computing derivatives and curvature values where level sets are densely bunched together.

This class is templated over the image type which represents the level set.

This class supports narrowbanding. If the input narrowband is provided, the algorithm will only locate the level set within the input narrowband. For the output, the reinitialize level set is only valid for a distance of OutputNarrowBandwidth / 2 of either side of the level set of interest.

Implementation of this class is based on Chapter 11 of "Level Set Methods and Fast Marching Methods", J.A. Sethian, Cambridge Press, Second edition, 1999.

Member Function Documentation

template<class TLevelSet> virtual void itk::ReinitializeLevelSetImageFilter< TLevelSet >::AllocateOutput (   )  [protected, virtual]

Reimplemented in itk::ExtensionVelocitiesImageFilter< TLevelSet, TAuxValue, VAuxDimension >.

template<class TLevelSet> virtual void itk::ReinitializeLevelSetImageFilter< TLevelSet >::EnlargeOutputRequestedRegion (  DataObject *   )  [protected, virtual]

Give the process object a chance to indictate that it will produce more output than it was requested to produce. For example, many imaging filters must compute the entire output at once or can only produce output in complete slices. Such filters cannot handle smaller requested regions. These filters must provide an implementation of this method, setting the output requested region to the size they will produce. By default, a process object does not modify the size of the output requested region. Reimplemented from itk::ProcessObject. Reimplemented in itk::ExtensionVelocitiesImageFilter< TLevelSet, TAuxValue, VAuxDimension >.

template<class TLevelSet> void itk::ReinitializeLevelSetImageFilter< TLevelSet >::GenerateData (  void   )  [protected, virtual]

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling ThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter an be threaded, it should NOT provide a GenerateData() method but should provide a ThreadedGenerateData() instead. See also: ThreadedGenerateData() Reimplemented from itk::ImageSource< TLevelSet >.

template<class TLevelSet> virtual void itk::ReinitializeLevelSetImageFilter< TLevelSet >::GenerateDataFull (   )  [protected, virtual]

Reimplemented in itk::ExtensionVelocitiesImageFilter< TLevelSet, TAuxValue, VAuxDimension >.

template<class TLevelSet> virtual void itk::ReinitializeLevelSetImageFilter< TLevelSet >::GenerateDataNarrowBand (   )  [protected, virtual]

Reimplemented in itk::ExtensionVelocitiesImageFilter< TLevelSet, TAuxValue, VAuxDimension >.

template<class TLevelSet> virtual void itk::ReinitializeLevelSetImageFilter< TLevelSet >::GenerateInputRequestedRegion (   )  [protected, virtual]

What is the input requested region that is required to produce the output requested region? The base assumption for image processing filters is that the input requested region can be set to match the output requested region. If a filter requires more input (for instance a filter that uses neighborhoods needs more input than output to avoid introducing artificial boundary conditions) or less input (for instance a magnify filter) will have to override this method. In doing so, it should call its superclass' implementation as its first step. Note that imaging filters operate differently than the classes to this point in the class hierachy. Up till now, the base assumption has been that the largest possible region will be requested of the input. This implementation of GenerateInputRequestedRegion() only processes the inputs that are a subclass of the ImageBase<InputImageDimension>. If an input is another type of DataObject (including an Image of a different dimension), they are skipped by this method. The subclasses of ImageToImageFilter are responsible for providing an implementation of GenerateInputRequestedRegion() when there are multiple inputs of different types. See also: ProcessObject::GenerateInputRequestedRegion(), ImageSource::GenerateInputRequestedRegion() Reimplemented from itk::ImageToImageFilter< TLevelSet, TLevelSet >.
