(e, f) the deformation field calculated by the algorithm (for better clarity the deformation
vectors have been scaled by a factor of two).

and target image and comparing those to the position predicted by the non-
rigid registration algorithm.

In carrying out validation, it is important to
consider the correspondence issues introduced in Chapter 2. An algorithm
