Detailed Description

template<class TInputImage, class TFeatureImage, class TSharedData = ConstrainedRegionBasedLevelSetFunctionSharedData< TInputImage, TFeatureImage, ScalarChanAndVeseLevelSetFunctionData< TInputImage, TFeatureImage > >>
class itk::ScalarChanAndVeseLevelSetFunction< TInputImage, TFeatureImage, TSharedData >

LevelSet function that computes a speed image based on regional integrals of probabilities.

This class implements a level set function that computes the speed image by integrating values on the image domain.
