itk::SegmentationLevelSetFunction< TImageType, TFeatureImageType > Class Template Reference
#include <itkSegmentationLevelSetFunction.h>
Detailed Description
template<class TImageType, class TFeatureImageType = TImageType>
class itk::SegmentationLevelSetFunction< TImageType, TFeatureImageType >
- This object defines the API for a class of function objects which perform level set based segmentations. The SegmentationLevelSetImageFilter objects use these SegmentationLevelSetFunction objects to perform the numerical calculations which move a level set front to lock onto image features.
- In order to create a working function object, you must subclass the CalculateSpeedImage method to produce a "feature image" that is used by the parent LevelSetFunction class as the PropagationSpeed for its calculations.

This global data cannot be kept in the instance of the equation object itself since the equation object must remain stateless for thread safety. The global data is therefore managed for each thread by the finite difference solver filters.

| virtual void itk::SegmentationLevelSetFunction< TImageType, TFeatureImageType >::ReverseExpansionDirection | ( | ) | [virtual] |
Determines whether Positive or Negative speed terms will cause surface expansion. This method flips the sign of all of the speed, advection, etc terms. By convention, filters should be written so that POSITIVE speed terms cause surface expansion. Calling this method will toggle between the standard POSITIVE EXPANSION convention and the nonstandard NEGATIVE EXPANSION convention.
IMPORTANT: When adding terms to the level-set equation through subclassing you may need to override this function so that your new terms will be properly adjusted.
