[Insight-users] Apply a known deformation

[Luis Ibanez]

Hi Gabri,


You will find example code that follows Karthik's suggestion at

                    Insight/Examples/Registration


Take a look at the files:

                    ThinPlateSplineWarp.cxx
                    LandmarkWarping2.cxx
   		   BSplineWarping1.cxx


You will find them described in the ITK Software Guide

        http://www.itk.org/ItkSoftwareGuide.pdf



    Regards,


        Luis
