[Insight-developers] changes in level set routines since ITK 3.4 breaks itk-snap

[Casey Goodlett]

Hi,

I have recently compiled itk-snap 1.6.0.1 against the latest version of ITK,
and the automatic segmentation routines in SNAP no longer behave correctly.
When initializing the segmentation routine with a bubble, the bubble does
not get correctly converted into a label map using newer versions of ITK,
and the level set evolution does not behave correctly.  Going back to ITK
3.4 fixes the problem.

I've noticed that there were changes made to the level set routines in ITK
with respect to bug 0006156 (
http://public.kitware.com/Bug/view.php?id=6156).  I've checked out CVS
of ITK before and after these changes and can
confirm that the problem came about in ITK between 2008-03-01 and
2008-03-06.

I tried toggling the ITK_DEPRECATED_LEVELSET_INTERPOLATION flag in the cmake
config but there was no effect on the problem.

I'm unsure how to solve the problem so that snap can be used against the
current version of ITK.  Can someone explain how the behavior of the level
set filters changed?

Thank you
