Detailed Description

template<class TLevelSet>
class itk::LevelSetNeighborhoodExtractor< TLevelSet >

Locate pixels of a particular level set.

LevelSetNeighborhoodExtractor locates a particular level set in the input level set. Specifically, the method Locate() fills two containers: one containing pixels immediately inside the contour defined by the level set and the other containing pixels immediately outside. For each located pixel, an estimated distance to the particular level set is also calculated.

The containers InsidePoints and OutsidePoints can then be used in FastMarchingImageFilter to produce a signed distance map from the specified level set.

This class is templated over the image type representing the level set.

This class supports narrowbanding. If a input narrowband is provided, the alogrithm will only search pixels within the narrowband.

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.
