Nonrigid morphological image registration & its practical issues
Marc Droske, Martin Rumpf, Carlo Schaller · 2004
We present a novel variational method to nonrigid registration of multimodal 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.
