We present a novel variational method to non rigid registration of multi-modal data. A suitable deformation will be determined via the minimization of a morphological, i.e., contrast invariant, matching functional along with an appropriate regularization energy. Here we want to give special focus on the practical issues involving scale-space methods, regularization of the corresponding gradient flow and hyperelastic regularization.
