#include <itkCurvesLevelSetFunction.h>
This function is used in CurvesLevelSetImageFilter to segment structures in images based on user supplied edge potential map.
\[ g(I) = 1 / ( 1 + | (\nabla * G)(I)| ) \]
\[ g(I) = \exp^{-|(\nabla * G)(I)|} \]
where \( I \) is image intensity and \( (\nabla * G) \) is the derivative of Gaussian operator.
