[Insight-users] quesition of itkShapeDetectionLevelSetImageFilter in 3D

[Luis Ibanez]

Hi Kingaza,


Thanks for posting the screen shots of your output.

It seems that the speed image is not being connected
correctly to the FastMarching filter.

Your manipulations of origin and spacing may easily
be part of the problem....


You may also have an problem with the scaling of the
speed image. Are you using values from 0.0 to 1.0 ??



Please post your code to the list.



   Thanks


      Luis
