[Insight-users] Rigid registration with translation restricted to single axis?

[g c]

Hi,

I would like to rigidly register two 2D images, where the translation
should be restricted to a single axis (say the x-axis). I suppose this
should be fairly straightforward, perhaps by modifying the
itk::TranslationTransform class? Has anyone already done this before?
Any suggestion appreciated.

Best regards,

George
