Detailed Description

template<class TImage>
class itk::VectorGradientNDAnisotropicDiffusionFunction< TImage >

This class is a simple extension of the GradientNDAnisotropicDiffusionFunction to pixel types of multiple components. Vector components are diffused separately, but diffusion of each component is limited by a conductance term which depends on all components.

For more information, please see GradientNDAnisotropicDiffusionFunction.

static void itk::LightObject::BreakOnError (  )  [static, inherited]

This method is called when itkExceptionMacro executes. It allows the debugger to break on error.

template<class TImage >
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.

template<class TImage >
virtual void itk::VectorAnisotropicDiffusionFunction< TImage >::CalculateAverageGradientMagnitudeSquared ( TImage *   )  [virtual, inherited]

Compute the average gradient magnitude squared.

template<class TImage >
virtual TimeStepType itk::AnisotropicDiffusionFunction< TImage >::ComputeGlobalTimeStep ( void *   )  const [inline, virtual, inherited]
