[Insight-users] GradientAnisotropicDiffusionImageFilter

[Luis Ibanez]

Hi Emin,

Please read the ITK Software Guide


   http://www.itk.org/ItkSoftwareGuide.pdf


in particular, you should read section 6.7 in
PDF-page 229.

You will find suggested values for 2D and 3D
images, and examples illustrating the output.

You may want to play with the example in

Insight/Examples/Filtering/
  GradientAnisotropicDiffusionImageFilter.cxx

Using as input the image

        Insight/Examples/Data/
           BrainProtonDensitySlice.png


In general you could be fine with something like


      Number of iterations : 5 to 50
      Conductance :          3.0
      Time step:             0.05

You may be able to reduce the number of iterations
(and hence the computation time) by increasing
conductance and/or time step, but at some point
you may hit the range of numerical instability.



   Regards,


      Luis
