Non-rigid registration of meshes

Actually, one more question, does anyone know the algorithm being applied for the deformable registration between the segments in Segment Registration? Is it Iterative Closest Points, or some variation thereof?

The method uses intensity-based b-spline registration of distance maps. See details at the links in this post:

align two segments to each other

Segment Registration extension supports non-linear warping (based on b-spline registration of distance maps). We tried various approaches and this worked the best for our applications. It was tested extensively on prostate US/MRI registration, used successfully in clinical work, and worked surprisingly well for other applications, too.

@stevenagl12

perform deformable registration after registration with fiducials, it is not warping the model at all?

You need to harden the landmark-based transform before starting the new registration.
