Detailed Description

template<typename TInput, typename TFeature, typename TSharedData>
class itk::RegionBasedLevelSetFunction< TInput, TFeature, TSharedData >

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

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

Based on the paper [22].

Author

Mosaliganti K., Smith B., Gelas A., Gouaillard A., Megason S.

This code was taken from the Insight Journal paper [87] that is based on the papers [86] and [85].

NOTE: The convention followed is inside of the level-set function is negative and outside is positive.

ComputeGlobalTerm()

template<typename TInput, typename TFeature, typename TSharedData>

ScalarValueType itk::RegionBasedLevelSetFunction< TInput, TFeature, TSharedData >::ComputeGlobalTerm ( const ScalarValueType & imagePixel, const InputIndexType & inputIndex )

Compute the global term as a combination of the internal, external, overlapping and volume regularization terms.

ComputeGlobalTimeStep()

template<typename TInput, typename TFeature, typename TSharedData>

TimeStepType itk::RegionBasedLevelSetFunction< TInput, TFeature, TSharedData >::ComputeGlobalTimeStep ( void * GlobalData ) const

overridevirtual

Computes the time step for an update given a global data structure. The data used in the computation may take different forms depending on the nature of the equations. 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.

Implements itk::FiniteDifferenceFunction< TInput >.

Compute the overlap term.

Parameters

[in]	featIndex
[out]	pr	= \( \prod_{i \neq j} H(\phi_i)\)

Returns

OverlapTerm = \( \sum_{i \neq j} H(\phi_i)\)

Implemented in itk::ScalarRegionBasedLevelSetFunction< TInputImage, TFeatureImage, TSharedData >.

Compute the overlap term.

Returns

Note

the volume regularization does not depend on the spacing. So the volume must be set in number of pixels (not in real world unit).

virtual ScalarValueType itk::RegionBasedLevelSetFunction< TInput, TFeature, TSharedData >::CurvatureSpeed ( const NeighborhoodType & , const FloatOffsetType & , GlobalDataStruct * = 0 ) const

The global data should also be initialized in this method.
