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

[Radu C. Popa]

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
