[Insight-users] CurvatureNDAnisotropicDiffusionFunction conductance question

[lucantiga at softhome.net]

Hi there, 
 I was reading the code for ComputeUpdate in
itkCurvatureNDAnisotropicDiffusionFunction.txx, and noticed that the
conductance term implemented is not that in the man page

\nabla \cdot \frac{\nabla f}{|\nabla f|}

but rather a scaled version of 

\exp{-\frac{|\nabla f|}{K}^2}

which is basically the same as used in 
itkGradientNDAnisotropicDiffusionFunction.txx

 Basides the fact that the documentation bug should be fixed,
is there a reason why the original conductance wasn't implemented?
 Thanks!

Luca
