Implements itk::FiniteDifferenceSparseImageFunction< TSparseImageType >.

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.

This function is called from LevelSetNormalImageFilter for all of the nodes to compute and store the flux vectors (first derivatives of the normal vectors. ComputeUpdateNormal then takes derivatives of the flux vectors. This way we avoid repeating the same flux computations.
Reimplemented from itk::FiniteDifferenceSparseImageFunction< TSparseImageType >.

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from itk::NormalVectorFunctionBase< TSparseImageType >.
|
inline |
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 107 of file itkNormalVectorDiffusionFunction.h.
|
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.
