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, TImageType >.

◆ CreateAnother()

template<typename TImageType, typename TFeatureImageType = TImageType>

virtual::itk::LightObject::Pointer itk::LaplacianSegmentationLevelSetFunction< TImageType, TFeatureImageType >::CreateAnother ( ) const

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightObject.

◆ GetNameOfClass()

template<typename TImageType, typename TFeatureImageType = TImageType>

const char * itk::LaplacianSegmentationLevelSetFunction< TImageType, TFeatureImageType >::GetNameOfClass ( ) const

overridevirtual

See also: LightObject::GetNameOfClass()

Reimplemented from itk::FiniteDifferenceFunction< TImageType >.

◆ 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 >.

Definition at line 66 of file itkLaplacianSegmentationLevelSetFunction.h.

◆ 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 >.

Definition at line 82 of file itkLaplacianSegmentationLevelSetFunction.h.
