[Insight-users] TPS landmark fitting with itk

[Luis Ibanez]

Hi Raja,



A) Bad news:
Nope, the itkThinPlateSplineKernelTransform  is not the class that
you should use for this task.



B) Good news:
Nick Tustison recently posted to the Insight Journal the class that
will solve your problem:


            itkBSplineScatteredDataPointSetToImageFilter



You will find interesting to read the paper at:

                    http://hdl.handle.net/1926/140



and you will find the classes in the directory:


     Insight/Code/Review

Just make sure that you use the ITK 3.10 release or a more recent
CVS checkout.



     Regards,


         Luis
