Summary0008795: itkMultiResolutionPyramidImageFilter broke backward-compatibility: smoothing by default
DescriptionThis filter can do smoothing before sub-sampling. Smoothing used to be disabled by default.

On Dec 17 2008 smoothing was enabled accidentally, which incurs in a computation time penalty, and results in non-backward-compatible behavior. This was fixed in the main trunk on Jan 26 2009. Now it should be fixed in the ITK 3.12 branch.
Steps To Reproduce
Additional InformationThe commit of December 17 2008:

http://www.itk.org/cgi-bin/viewcvs.cgi/Code/Algorithms/itkMultiResolutionPyramidImageFilter.txx?root=Insight&r1=1.26&r2=1.27&sortby=date [^]

broke backward compatibility, by enabling the use of smoothing by default.
(and operation that is computationally demanding).

The change was reverted in the main trunk on Janury 26 2009:

http://www.itk.org/cgi-bin/viewcvs.cgi/Code/Algorithms/itkMultiResolutionPyramidImageFilter.txx?root=Insight&r1=1.29&r2=1.30&sortby=date [^]

We must apply the same patch (of Jan 26 2009) to the ITK 3.12 branch
