This method is called when itkExceptionMacro executes. It allows the debugger to break on error.
| virtual void itk::AnisotropicDiffusionFunction< TImage >::CalculateAverageGradientMagnitudeSquared | ( | ImageType * | ) | [pure virtual, inherited] |
This method is called before each iteration. It calculates a scalar value that is the average of the gradient magnitude squared at each pixel in the output image (intermediate solution). The average gradient magnitude value is typically used in the anisotropic diffusion equations to calibrate the conductance term.

| virtual TimeStepType itk::AnisotropicDiffusionFunction< TImage >::ComputeGlobalTimeStep | ( | void * | ) | const [inline, virtual, inherited] |
Returns the time step supplied by the user. We don't need to use the global data supplied since we are returning a fixed value.

| 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.
