<DIV><FONT face=Arial size=2>I am trying to register CT and MRI 3D images using
a program apdated from MultiResMIRegistration, using Viola-Wells MI,
QuaternionRigidTransform and CenteredTransformInitializer, but the registration
result is pathetic, I attached the optimization monitoring file to the email and
type the parameters value in the following, I would be very grateful if you
could give me any suggestion.</FONT></DIV>
