[Insight-users] 2nd try: 3D point-set registrations

[Miller, James V (Research)]

I believe this would fit into ITK as a PointSetToSpatialObject 
registration method. It looks like that combination in not 
currently in ITK.  The UNC crew should be able to give some pointers
on what would be involved in adding this to ITK.

Hi,

Please help in finding the "final" answers to these questions:

1. is it possible in ITK to fit-register a 3D **model** (e.g., an ellipsoid)
to a "cloud" of **points** (i.e., the nodes of a 3D mesh)?

2. the same question for a 3D cloud of points to a 3D cloud of points, when
the points are not given as pairs as per landmark registration


Is it correct to conclude that?:

->1. the 3D model-to-mesh-points is not possible; instead, only the
model-to-image (gray levels) solution is readily available

->2. the solution for mesh-points-to-mesh-points is to use the metric
IterativeClosestPointMetric

Thank you in advance.

Regards,

Radu
