[Insight-users] BSpline Deformable Registration with ITK4

[Nick Tustison]

Hi Sebastian,

You can find a working example of the new registration framework 
with the following core classes

https://github.com/stnava/ANTs/blob/master/Examples/antsRegistration.cxx
https://github.com/stnava/ANTs/blob/master/Examples/itkantsRegistrationHelper.h
https://github.com/stnava/ANTs/blob/master/Examples/itkantsRegistrationHelper.hxx

It is quite comprehensive in that it includes code for setting up 
B-spline registration as well as most other linear and deformable 
registration possibilities in case you were interested in exploring
other features.

Nick
