Detailed Description

template<typename TImage>
class itk::CurvatureFlowFunction< TImage >

This class encapsulate the finite difference equation which drives a curvature flow denoising algorithm.

This class uses a zero flux Neumann boundary condition when computing derivatives near the data boundary.

This class operates as part of the finite difference solver hierarchy.

Member Function Documentation

◆ ComputeGlobalTimeStep()

template<typename TImage >
TimeStepType itk::CurvatureFlowFunction< TImage >::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.

Currently, this function returns the user specified constant time step.

Todo:
compute timestep based on CFL condition.

Implements itk::FiniteDifferenceFunction< TImage >.

◆ ComputeUpdate()

template<typename TImage >
PixelType itk::CurvatureFlowFunction< TImage >::ComputeUpdate ( const NeighborhoodType neighborhood,
void *  globalData,
const FloatOffsetType offset = FloatOffsetType(0.0) 
)
override

This method computes the solution update for each pixel that does not lie on a the data set boundary.

◆ CreateAnother()

template<typename TImage >
virtual::itk::LightObject::Pointer itk::CurvatureFlowFunction< TImage >::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.

Reimplemented in itk::MinMaxCurvatureFlowFunction< TImage >.

◆ GetGlobalDataPointer()

template<typename TImage >
void* itk::CurvatureFlowFunction< TImage >::GetGlobalDataPointer ( ) const
inlineoverridevirtual

Returns a pointer to a global data structure that is passed to this object from the solver at each calculation. The idea is that the solver holds the state of any global values needed to calculate the time step, while the equation object performs the actual calculations. The global data should also be initialized in this method.

Implements itk::FiniteDifferenceFunction< TImage >.

Definition at line 93 of file itkCurvatureFlowFunction.h.

◆ GetNameOfClass()

template<typename TImage >
virtual const char* itk::CurvatureFlowFunction< TImage >::GetNameOfClass ( ) const
virtual

Run-time type information (and related methods)

Reimplemented from itk::FiniteDifferenceFunction< TImage >.

Reimplemented in itk::BinaryMinMaxCurvatureFlowFunction< TImage >, and itk::MinMaxCurvatureFlowFunction< TImage >.

◆ GetTimeStep()

template<typename TImage >
const TimeStepType& itk::CurvatureFlowFunction< TImage >::GetTimeStep ( ) const
inline

Get the time step parameter

Definition at line 120 of file itkCurvatureFlowFunction.h.

◆ New()

template<typename TImage >
static Pointer itk::CurvatureFlowFunction< TImage >::New ( )
static

Method for creation through the object factory.

◆ ReleaseGlobalDataPointer()

template<typename TImage >
void itk::CurvatureFlowFunction< TImage >::ReleaseGlobalDataPointer ( void *  GlobalData) const
inlineoverridevirtual

When the finite difference solver filter has finished using a global data pointer, it passes it to this method, which frees the memory. The solver cannot free the memory because it does not know the type to which the pointer points.

Implements itk::FiniteDifferenceFunction< TImage >.

Definition at line 106 of file itkCurvatureFlowFunction.h.

◆ SetTimeStep()

template<typename TImage >
void itk::CurvatureFlowFunction< TImage >::SetTimeStep ( const TimeStepType t)
inline

Set the time step parameter
