[Insight-users] Gradient Anisotropic Diffusion

[Mathieu Malaterre]

Hi all, Hi Luis,

   As you suggested in:
http://www.itk.org/pipermail/insight-users/2003-February/002580.html


I tried first option (A). But I couldn't find no good paramaters to have 
a closed surface.

See for differents sigma value :
http://www.creatis.insa-lyon.fr/~malaterre/vtk/vessel_sigma5.png
and
http://www.creatis.insa-lyon.fr/~malaterre/vtk/vessel_sigma10.png

So I tried option (B). I tried first an edge preserving filter which is 
to say GradientAnisotropicDiffusionImageFilter. I browse the 
ItkSoftwareGuid.pdf and on p96, chap 5. (Filtering) you wrote:

[Typical values for the time step are 0.25 in 2D images and 0.125 in 3D 
images.]

But if you browse now the source code of this filter there is no mention 
to TimeStep ?
What did I misunderstood ? What are the real parameters that affect this 
filter ?


thanks,
mathieu
