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.
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
