Hi Ravi,

You may want to use the RigidTransforms:

http://www . itk . org/Insight/Doxygen/html/classitk_1_1Euler3DTransform . html
http://www . itk . org/Insight/Doxygen/html/classitk_1_1VersorRigid3DTransform . html
with any optimizer


or

http://www . itk . org/Insight/Doxygen/html/classitk_1_1QuaternionRigidTransform . html
and it associated optimizer
http://www . itk . org/Insight/Doxygen/html/classitk_1_1QuaternionRigidTransformGradientDescentOptimizer . html

This last combination is probably the best option.


Regards,


   Luis
