[Insight-users] Deformable transform

[Luis Ibanez]

Hi Ganesh,

You may want to use the

http://www.itk.org/Doxygen/html/classitk_1_1WarpImageFilter.html

You may also find useful the "vv" application:

                   http://www.creatis.insa-lyon.fr/rio/vv

It provides functionalities for visualizing the outcome of deformable
registration, including the overlapping of the deformation field.


    Regards,


          Luis
