Fluid dynamics based registration was first introduced by Christensen (5). Later Bro-Nielsen et al. (4) suggested speedups of the computational costly method by using digital filters. I implemented the registration approach using different solvers for the solution of the core problem of the fluid-dynamics based registration - the solution of the Navier-Stokes-Equation. The implementation is available (9) under the terms of the GNU General Public License (1)
