Code/Algorithms/itkBayesianClassifierImageFilter.txx-
this->GetOutput()->SetRegions( membershipImage->GetBufferedRegion() );
Code/Algorithms/itkBayesianClassifierImageFilter.txx:
this->GetOutput()->SetSpacing( membershipImage->GetSpacing() );
Code/Algorithms/itkBayesianClassifierImageFilter.txx-
this->GetOutput()->SetOrigin(  membershipImage->GetOrigin() );
Code/Algorithms/itkBayesianClassifierImageFilter.txx-
this->GetOutput()->Allocate();

NOTICE:  The output of this filter does not set the Direction!!!!
this->GetOutput()->SetDirection(  membershipImage->GetDirection() );
=======================================================

Unfortunately this seems like a very common problem throughout ITK.   It is
my assumption that most filters that: a) take input image, b) do something
to the intensity values, c) generate and output image; will behave in such a
way that the output image has the same origin, spacing, size, AND direction
as the input image.  Filters  that: a)take an input image, b) take
parameters for desired output physical space defintion, c) generate the new
output image; must have options for setting Spacing, Origin, AND Direction.

Experimental build:

I hope to have the code committed and bugs reported in about 1 hour.

<TITLE>Bugs with respect to ITK_IMAGE_BEHAVES_AS_ORIENTED_IMAGE </TITLE>

Luis, 
 
I'm sorry to spring this on you just hours after the release, but I disco=
vered several bugs when ITK_IMAGE_BEHAVES_AS_ORIENTED_IMAGE is turned on, a=
nd images with different directions are used. 
 
I'm working on a patch right now, but it does touch many many files. &nbs=
p;So far my tests have shown that regression tests pass both with or withou=
t setting the output directions. &nbsp;The problem showed up when attemptin=
g to register images that have different orientations, spacing's, size, and=
 origins. &nbsp;I think that our test data is too uniformly defined to catc=
h these problems.
