[Insight-users] Question for LaplacianSegmentationLevelSetFunction

[zhao yong qiang]

Hi all,

   

         I read the code of this class, and I am puzzled.

In the base class LevelSetFunction, m_LaplacianSmoothingWeight is set 0.
But in the class of LaplacianSegmentationLevelSetFunction, I did not
find where this weight was set. So I don't understand how and where to
get the laplacian of the image.

I think that from LaplacianSegmentationLevelSetFunction,we can get the
following PDE,

dC/dt = Advection term + Curvature term.

Is it right?
