[Insight-users] 3d registration using ITK mesh

[Luis Ibanez]

Hi Nadia,

There are multiple ways to do this.

A) you could extract a surface from the 3D image
    (your stack of 3D images) and then register it
    with the mesh extracted from the VRML file.

    You may want to use Iterative Closest Point (ICP) as
    illustrated in the examples in:


      Insight/Examples/Patented
         IterativeClosestPoint1.cxx
         IterativeClosestPoint2.cxx
         IterativeClosestPoint3.cxx

     or you can fully do this in VTK with the:
http://www.vtk.org/doc/nightly/html/classvtkIterativeClosestPointTransform.html



B) You can use ImageToPointSet registration methods.
    as illustrated in:

       itkPointSetToImageRegistrationTest_1.cxx




Regards,


    Luis
