[Insight-users] Registration and Euler3DTransform

[Luis Ibanez]

Hi Michael,

The Euler3DTransform is only appropriate for small rotations.
In that conditions you could use any of the GradientDescent
optimizers.

Please keep in mind that this parameterization of the transform
is very non-linear.  What the optimizer is doing is to perform
a linear approximation at every step. So, try keeping the step
length at a very conservative value.


Regards,


   Luis
