Detailed Description

template<class TLevelSet, class TAuxValue, unsigned int VAuxDimension = 1>
class itk::LevelSetVelocityNeighborhoodExtractor< TLevelSet, TAuxValue, VAuxDimension >

Locate pixels of a particular level set.

LevelSetVelocityNeighborhoodExtractor extends the functionality of LevelSetNeighborhoodExtractor by also extracting the values of velocity variables at the specified level set. Specifically, it populates two containers: one containing the value of velocity variables immediately inside the contour defined by the level set and the other containing values for velocity variables immediately outside.

The containers AuxInsideValues() and AuxOutsideValues() can be used in conjunction with Superclass::InsidePoints() and Superclass::OutsidePoints() in FastMarchingExtensionImageFilter to produce images which extends the velocity variables smoothly from the specified level set.

This class is templated over the image type representing the level set, the type of the auxiliary/velocity variables and the number of auxiliary/velocity variables.

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