[Insight-users] Scale, Rotation & Translation Transform

[Andy Eow]

Hi Luis,

I'm looking to register two 3D volumes in which the target cortex might be of different sizes. As such, I need a transform that finds the optimal parameters for translation, rotation & scaling (no skewing). I've noticed that most 3D rigid transforms either do not provide for scaling or provides too many degrees of freedom with skewing. Does ITK have a transform filter that just does translation, rotation & scaling only? 

Thanks!

Cheers,
Andy
