[Insight-users] Point Set Rigid Registration

Hello!

I want to register 2 point sets with different number of points. I am using
the example code 'IterativeClosestPoint2.cxx' but it not giving
satisfactory results. Does this code work for point sets without one-to-one
correlation? The code uses Euler3DTransform, EuclideanDistancePointMetric
and LevenbergMarquardtOptimizer. I'm certain that only rigid registration
is required at this stage. What other transforms, metrics and optimizers
can work in such a scenario? I have initialized the transform to expected
translation and rotation values using the SetRotation and SetTranslation
methods. But the results of the registration are way off the mark. Any
suggestions will be greatly appreciated :)

Thanks,
Nirav.
