[ITK] [ITK-users] Fwd: 3D registration with level set motion

[Samuel Gerber]

That looks like there should be enough overlap.

Do you get the exception while the registration is running? In that case it
might be that during the registration the transform pushes the images away
from each other until there is not enough overlap. What kind of optimizer
are you using? You might need to adjust the step size of your optimizer.
