Hi Xavier,

Please look at the example:


This illustrate how to use multi-resolution BSpline grids
in a deformable registration scheme.

This is illustrated here in 2D, but the same is applicable
to ND. ITK is N-Dimensional.

For examples of BSpline deformable registration in 3D you
may want to look at
