Member Function Documentation

◆ CalculateSpeedImage()

template<typename TImageType , typename TFeatureImageType = TImageType>
void itk::LaplacianSegmentationLevelSetFunction< TImageType, TFeatureImageType >::CalculateSpeedImage ( )
overridevirtual

This method must be defined in a subclass to implement a working function object. This method is called before the solver begins its work to produce the speed image used as the level set function's Propagation speed term. See LevelSetFunction for more information.

Reimplemented from itk::SegmentationLevelSetFunction< TImageType, TFeatureImageType >.

◆ Initialize()

template<typename TImageType , typename TFeatureImageType = TImageType>
void itk::LaplacianSegmentationLevelSetFunction< TImageType, TFeatureImageType >::Initialize ( const RadiusType &  r)
inlineoverridevirtual

This method creates the appropriate member variable operators for the level-set calculations. The argument to this function is a the radius necessary for performing the level-set calculations.

Reimplemented from itk::LevelSetFunction< TImageType >.

◆ New()

template<typename TImageType , typename TFeatureImageType = TImageType>
static Pointer itk::LaplacianSegmentationLevelSetFunction< TImageType, TFeatureImageType >::New ( )
static

Method for creation through the object factory.

◆ SetAdvectionWeight()

template<typename TImageType , typename TFeatureImageType = TImageType>
void itk::LaplacianSegmentationLevelSetFunction< TImageType, TFeatureImageType >::SetAdvectionWeight ( const ScalarValueType  value)
inlineoverridevirtual

The Laplacian level set does not use an advection term. We clamp the value to ZERO here because a superclass may try to set it otherwise. in fact, SegmentationLevelSetImageFilter tries to set it when SetFeatureScaling is called.

Reimplemented from itk::LevelSetFunction< TImageType >.
