[Insight-users] Problem implementing GradientAnisotropicDiffusionImageFilter

[O'Connor, Michael]

Hello Luis,
     The pixel spacing is .2 mm.   I did not SetSpacing in ITK code.   Thanks for the insight.   I will check that out.

Regards,
   Michael

Hi Michael,

What is the pixel spacing of your image ?

I believe that the ITK implementation may
be taking the pixel spacing into account
when using the value of conductance.


   Please let us know,


             Thanks


                       Luis
