Detailed Description

template<class TInput, class TFeature, class TSharedData>
class itk::RegionBasedLevelSetFunction< TInput, TFeature, TSharedData >

LevelSet function that computes a speed image based on regional integrals.

This class implements a level set function that computes the speed image by integrating values on the image domain.

Based on the paper: 

   "An active contour model without edges"
    T. Chan and L. Vese.
    In Scale-Space Theories in Computer Vision, pages 141-151, 1999.
Author
Mosaliganti K., Smith B., Gelas A., Gouaillard A., Megason S.

This code was taken from the Insight Journal paper: 

"Cell Tracking using Coupled Active Surfaces for Nuclei and Membranes"
http://www.insight-journal.org/browse/publication/642
http://hdl.handle.net/10380/3055

That is based on the papers: 

"Level Set Segmentation: Active Contours without edge"

Computes the time step for an update given a global data structure. The data used in the computation may take different forms depending on the nature of the equations. 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.

Returns a pointer to a global data structure that is passed to this object from the solver at each calculation. The idea is that the solver holds the state of any global values needed to calculate the time step, while the equation object performs the actual calculations.

The global data should also be initialized in this method.
