[Insight-users] Inverse of ScaleSkewVersor3DTransform

[Ranjan, Sohan (Research)]

I am doing registration using the ScaleSkewVersor3DTransform. As per ITK
registration convention, the transform returned is from the fixed image space 
to the moving image space. I am not using the resample filter for resampling
the moving image due to certain reasons, so I need to find an inverse of the
transform myself. But it looks like that the inverse for ScaleSkewVersor3DTransform
is not defined.

Can someone suggest how should I go about constructing the inverse?
