<DIV><FONT face=Arial size=2>I use the transform and the optimizer
(VersorRigid3DTransform, VersorRigid3DTransformOptimizer, and
CenteredTransformInitializer) to perforom 3D rigid registration on my data, and
I notice that in itk example, the image pyramid isn't used for
the 3D registration. I tried adding that to my registration program, but
it produced worsely registered output. Does anyone one know why?
Does that mean I shouldn't use image pyramid technique for registering 3D
data?</FONT></DIV>
