Hi users,

I'm using ITK registration framework for a while now, and so far, it
worked great.
Since I upgrade my ITK build to 2.8.1, I had problems with the framework.

I built the same source code from ITK 1.8.0, ITK 2.0 and ITK 2.8.1.
I ran the program with the corresponding ITKCommon.dll and had different
results.

With ITK 1.8.0 and 2.0, registration converged and gave me an excellent
result.
With 2.8.1, registration stopped because volumes weren't overlapping
anymore...
What's the matter with this release?

I did not try with the new 3.0 release, and so don't know if this behavior
was corrected.

These are the components I use:

itkImageRegistrationMethod.h
itkVersorRigid3DTransform.h
itkVersorRigid3DTransformOptimizer.h
itkCenteredVersorTransformInitializer.h
itkMeanSquaresImageToImageMetric.h
itkLinearInterpolateImageFunction.h
itkResampleImageFilter.h

Let me know if a bug report is necessary... or if I missed something new
in newer releases.

Thanks,

Laurent.
