Detailed Description

template<class TImageType, class TSparseImageType>
class itk::LevelSetFunctionWithRefitTerm< TImageType, TSparseImageType >

This class extends the LevelSetFunction class by adding a grow term based on a target curvature stored in a sparse image.

We extend the LevelSetFunction class to add a refitting term. This refitting term forces the curvature of the level set interface to match a prescribed curvature. The prescribed curvature is provided in a sparse image format. The NodeType for the sparse image should contain the member variables m_Curvature and m_CurvatureFlag. The refitting term is defined as part of the propagation term of the original LevelSetFunction. To this purpose we defined the PropagationSpeed method which computes the refitting term and also adds to this term the value returned by the new virtual OtherPropagationSpeed. Therefore, classes derived from this class MUST NOT overwrite the PropagationSpeed method. Instead classes wishing to define a prapagtion term must define OtherPropagationSpeed.
IMPORTANT
Subclasses MUST NOT overwrite the PropagationSpeed method. Define OtherPropagationSpeed instead.

Member Function Documentation

template<class TImageType , class TSparseImageType >
ScalarValueType itk::LevelSetFunctionWithRefitTerm< TImageType, TSparseImageType >::ComputeCurvature ( const NeighborhoodType ) const [protected]

Computes the curvature of a level set neighbothood in a way that matches the curvature computation from normal vectors.

template<class TImageType , class TSparseImageType >
virtual TimeStepType itk::LevelSetFunctionWithRefitTerm< TImageType, TSparseImageType >::ComputeGlobalTimeStep ( void *  GlobalData) const [virtual]

Computes the time step for an update given a global data structure. This calls the ComputeGlobalTimeStep method defined in LevelSetFunction and then imposes our own restrictions for the refitting term on the returned value.

virtual::itk::LightObject::Pointer itk::LevelSetFunctionWithRefitTerm< TImageType, TSparseImageType >::CreateAnother ( void  ) 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.
