Detailed Description

template<typename TInputImage, typename TFeatureImage, typename TSharedData>
class itk::ScalarRegionBasedLevelSetFunction< TInputImage, TFeatureImage, 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. NOTE: The convention followed is inside of the level-set function is negative and outside is positive.

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"
https://www.insight-journal.org/browse/publication/642

That is based on the papers:

"Level Set Segmentation: Active Contours without edge"
https://www.insight-journal.org/browse/publication/322

and

"Level set segmentation using coupled active surfaces"
https://www.insight-journal.org/browse/publication/323
