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.
