[ITK-users] How to get the displacementfield from compositetransform?

[Francois Budin]

Hello Wang,

What was the exception message that you were getting? Did you try the
TransformToDisplacementFieldFilter with only one simple transform (such as
an affine transform) to see if your implementation was working in that
case? Did you specify a size or a reference image for the
TransformToDisplacementFieldFilter?

Hope this helps,
Francois
