Prof. Nikos Paragios (Ecole Centrale Paris), lecture 2
Prof. Nikos Paragios (Ecole Centrale Paris, France) was one of the speakers of Medical Imaging Summer School (Sicily, July 28-August 1, 2014), here you can find his lecture 2: "Deformable registration: setting the state of the art through coupling of iconic/geometric methods using discrete models".
Abstract. In this lecture we introduce a generic formalism for solving linear/non-linear registration that is able to account for various type of deformations, different similarity metrics and is able to integrate information coming from images with geometry (landmarks). This will be achieved through an interconnected graphical model coupling image matching constraints with landmarks correspondences.
Such a graphical model will encode similarity on singleton costs, smoothness on intra-graph pair-wise terms and consistency/coupling of iconic/geometric information through inter-graph pair-wise connections.
In order to impose linearity constraints higher order terms will be also considered. The resulting theoretical formulation can deal with linear, non-linear, mono-modal/multi-modal 2D-2D/3D-3D/2D-to-3D registration and once endowed with efficient optimization methods would provide state of the art results when efficiency vs precision is considered.
