Hi,

I'm using the itkRecursiveMultiResolutionPyramidImageFilter and I have
some problems with this filter:
It seems that this filter smoothes my image that much before resampling,
that I get an almost homogenous image. If I take the "smoother" out of
the filter (  shrinker->SetInput( caster->GetOutput() ); on line 83),
then everything works fine. Also if I set the variance very small
(variance[idim] = 0.01; on line 114) the result is okay.
Can you explain me why this smoother is not working for my image and why
the variance is chosen as it is?

Thanks,
Corinne

ps: I have a 50x50x50 image with origin {3.37776, 1.73713, 3.37776} and
spacing {0.0965074, 0.0965074, 0.0965074}.
