[Insight-users] aligning two contoursets

[Karthik Krishnan]

Yogish:

You should take a look at the Robust Point Matching algorithm from Chui 
and Anand Rangarajan:
  H.  Chui and Anand Rangarajan, "A new algorithm for non-rigid point 
matching", CVPR, 00

It solves the alignment problem with both rigid and non-rigid variants 
for arbitrary number of source and target points, with point 
correspondances being unknown. It is also fairly resilient to outliers. 
If you are looking for readily available source code, its available as a 
part of the BioImageSuite, in the form of a VTK algorithm. Look for 
source files of hte form vtk*RPM* and produces a vtkTransform for you.
