[Insight-users] 3D rigid registration

[Grace Chen]

Hi,

If I center just one image and shift another image....The result is quite
different (slice shift 2 slices forward) from if I don't center any input
images....

Can some ITK people please tell me if I should center input images at all??

Grace
