[Insight-users] How to concatenate itk transformations

[Luis Ibanez]

Hi Jian,

In ITK


   a) you can compose consecutive Affine transforms together,

   b) you can't compose two BSpline transforms

   c) you can set an Affine transform as the Bulk transform
              of a BSpline transform (which is equivalent to
              a pre-composition)



   Regards,


       Luis
