[Insight-users] about BSpline transform based on the PointSet Data object

[Luis Ibanez]

Hi Yixun,

The registration framwork for PointSet to PointSet registration
in ITK allows you to use any of the available transforms.

You can certainly use the BSplineDeformableTransform as the
transform in this registration.

Note that just like in the case of images, you will obtain better
results if you first solve the misregistration using simple transforms
and then fix the residuals using a more complex transform.

For example, you could first register using a RigidTransform, then
and Affine transform, and then finally use a BSpline transform.


You may want to look at the IterativeClosestPoint examples
available in


    Insight/Registration/
               IterativeClosestPoint1.cxx
               IterativeClosestPoint2.cxx
               IterativeClosestPoint3.cxx


Regards,


   Luis
