Member Function Documentation
| static void itk::LightObject::BreakOnError | ( | ) | [static, inherited] |
This method is called when itkExceptionMacro executes. It allows the debugger to break on error.
| virtual TimeStepType itk::CurvatureFlowFunction< TImage >::ComputeGlobalTimeStep | ( | void * | GlobalData | ) | const [virtual, inherited] |
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 >.
| const NeighborhoodScalesType itk::FiniteDifferenceFunction< TImage >::ComputeNeighborhoodScales | ( | ) | const [inherited] |
Compute the scales that weight the neighborhood during difference operations to properly account for spacing and neighborhood radius
| virtual PixelType itk::BinaryMinMaxCurvatureFlowFunction< TImage >::ComputeUpdate | ( | const NeighborhoodType & | neighborhood, | |
| void * | globalData, | |||
| const FloatOffsetType & | offset = FloatOffsetType(0.0) | |||
| ) | [virtual] |
This method computes the solution update for each pixel that does not lie on a the data set boundary.
Reimplemented from itk::MinMaxCurvatureFlowFunction< TImage >.
| virtual Pointer itk::LightObject::CreateAnother | ( | ) | const [virtual, inherited] |
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.

| virtual void itk::LightObject::Delete | ( | ) | [virtual, inherited] |
Delete an itk object. This method should always be used to delete an object when the new operator was used to create it. Using the C delete method will not work with reference counting.
| virtual void* itk::CurvatureFlowFunction< TImage >::GetGlobalDataPointer | ( | ) | const [inline, virtual, inherited] |
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.

Definition at line 109 of file itkCurvatureFlowFunction.h.
| virtual void itk::FiniteDifferenceFunction< TImage >::InitializeIteration | ( | ) | [inline, virtual, inherited] |
This method allows the function to set its state before each iteration of the finite difference solver (image filter) that uses it. This is a thread-safe time to manipulate the object's state.
An example of how this can be used: the Anisotropic diffusion class of FiniteDifferenceFunctions use this method to pre-calculate an average gradient magnitude across the entire image region. This value is set in the function object and used by the ComputeUpdate methods that are called at each pixel as a constant.
