Hi all,

   When I read the document of
AnisotropicFourthOrderLevelSetImageFilter, I am confused that what the
function of fourth order level set is.

Does this filter just implement the surface diffusion algorithm or
evolve the isosurface? Can someone tell me where the reference of this
filter?

Thanks in advance!
