[Insight-users] What is the role of landmarks in FEM registration

[Luis Ibanez]

Hi Yoav,

The landmarks are intended to constrain the deformation field
in certain locations.

The rest of the deformation field will be driven by the "artificial"
forces excerted by local evaluations of the metrics (similar to a
block-matching algorithm).



    Regards,


        Luis
