[Insight-users] BSpline - deformable transformation with default multiresolution framework

[Luis Ibanez]

Hi Markus,

You are correct in your observation.

The approach of using a multi-resolution BSpline grid is a different
mechanism than the one used in the standard multi-resolution framework.

In this case, as you pointed out, we are refining the transform itself.

At this point there is no direct way of integrating the BSpline multi
resolution with the pyramidal framework for multi-resolution
registration. It is, however, a very interesting undertaking and it will
be worth to invest some time on it if you find that in alignment with
your current work.

Please let us know if you need any help with the details of setting
up such a framework.



     Thanks


        Luis
