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.
