#include <itkExtensionVelocitiesImageFilter.h>

Detailed Description

template<typename TLevelSet, typename TAuxValue = float, unsigned int VAuxDimension = 1>
class itk::ExtensionVelocitiesImageFilter< TLevelSet, TAuxValue, VAuxDimension >

Extend velocities smoothly from a particular level set.

ExtensionVelocitiesImageFilter extends velocities smoothly from a particular level set.

This class is templated over the image type which represents the level set, the type of the velocity and the number of velocities to be extended.

This class supports narrowbanding. If the input narrowband is provided, the algorithm will only locate the level set within the input narrowband. For the output, the extended velocity is only valid for a distance of OutputNarrowBandwidth / 2 of either side of the level set of interest.

Implementation of this class is based on Chapter 11 of "Level Set Methods and Fast Marching Methods", J.A. Sethian, Cambridge Press, Second edition, 1999.
