#include <itkCurvatureFlowFunction.h>
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.

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.
Implements itk::FiniteDifferenceFunction< TImage >.

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

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.

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.

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.
