Detailed Description

template<class TInputImage, class TCoordRep = float>
class itk::LevelSetCurvatureFunction< TInputImage, TCoordRep >

Calculate the mean curvature of a level set at a specified index.

LevelSetCurvatureFunction calculates the mean curvature of a level set at a specified index. This class is templated over the input image type and the coordinate representation type (e.g. float or double).

Reference: "Level Set Methods and Fast Marching Methods", J.A. Sethian, Cambridge Press, Chapter 6, Second edition, 1999.

Possible improvements:

• the use of Neighborhood operators may improve efficiency.
