[Insight-users] fem registration filter

[Luis Ibanez]

Hi Janiv,

In addition to the FEM-Based deformable registration
you may also want to look at the BSplineTransform
that can be used for performing deformable registraion.

--

Regarding initialization by using manually selected
Landmarks you may want to look at the example

        Insight/Examples/Registration/
                             LandmarkWarping2.cxx



Regards,



      Luis
