Detailed Description

template<class TImageType, class TFeatureImageType>
class itk::VectorThresholdSegmentationLevelSetFunction< TImageType, TFeatureImageType >

This function is used in VectorThresholdSegmentationLevelSetImageFilter to segment structures in images based on the Mahalanobis distance.

CREDITS
This class was contributed to ITK by Stefan Lindenau http://www.itk.org/pipermail/insight-users/2003-December/005969.html
SegmentationLevelSetFunction is a subclass of the generic LevelSetFunction.
It useful for segmentations based on intensity values in an image. It works by constructing a speed term (feature image) with positive values inside an intensity window (between a low and high threshold) and negative values outside that intensity window. The evolving level set front will lock onto regions that are at the edges of the intensity window.
Image $ f(x) $ is thresholded pixel by pixel using threshold $T$ according to the following formula.

\[ f(x) = T - MahalanobisDistance(x) \]

This global data cannot be kept in the instance of the equation object itself since the equation object must remain stateless for thread safety. The global data is therefore managed for each thread by the finite difference solver filters.
