The Free-Form Deformation (FFD) algorithm is a widely-used approach for non-rigid registration. Modifications have previously been proposed to ensure topology preservation and invertibility within this framework. However, in practice, none of these yield the inverse transformation itself, and one loses the parsimonious B-spline parameterisation. © 2012 IEEE.
