| void * | globalData, | |||
| const FloatOffsetType & | offset = FloatOffsetType(0.0) | |||
| ) | [pure virtual, inherited] |
This method is called by a finite difference solver image filter at each pixel that does not lie on a data set boundary. The width of the data set boundary is defined by the width of the neighborhood being evaluated.
The neighborhood argument is the neighborhood data. The globalData argument is a pointer to a data structure that holds values that need to be persistent across calls to this function, but cannot be stored in the function object itself for thread-safety reasons. Examples are values needed to compute the time-step for an iteration of the solver.
| virtual PixelType itk::FiniteDifferenceSparseImageFunction< TSparseImageType >::ComputeUpdate | ( | const NeighborhoodType & | , | |
| void * | , | |||
| const FloatOffsetType & | ||||
| ) | [inline, virtual, inherited] |
This function is not called from the FiniteDifferenceSparseImageFilter class because we need to work with neighborhoods of pointers to data variables instead of neighborhoods of data directly. This function is replaced by the ComputeSparseUpdate function.
Definition at line 83 of file itkFiniteDifferenceSparseImageFunction.h.
| virtual Pointer itk::LightObject::CreateAnother | ( | ) | const [virtual, inherited] |

Reimplemented in itk::Object.
| 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.

Definition at line 106 of file itkLightObject.h.
| TimeStepType itk::NormalVectorFunctionBase< TSparseImageType >::GetTimeStep | ( | ) | const [inline, inherited] |
Returns the time step.
Definition at line 97 of file itkNormalVectorFunctionBase.h.
| virtual void itk::FiniteDifferenceFunction< TSparseImageType >::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.

This method sets the conductance parameter used in anisotropic filtering. Useful values for processing 2D and 3D shapes are between 0.1 and 0.25. Lower values preserve more shape features, higher values smooth more. As the conductance parameter large, the processing becomes isotropic. Default is 0.
Definition at line 105 of file itkNormalVectorDiffusionFunction.h.
| void itk::NormalVectorDiffusionFunction< TSparseImageType >::SetNormalProcessType | ( | int | npt | ) | [inline] |
This method is used to choose between isotropic/anisotropic filtering. A parameter value of 0 indicates isotropic diffusion and is the default. Parameter value 1 is anisotropic diffusion. When using anisotropic diffusion the conductance parameter should also be set.
