Image Registration under Varying Illumination: Hyper-Demons Algorithm

Abstract. The goal of this paper is to present a novel recipe for deformable image registration under varying illumination, as a natural extension of the demons algorithm. This generalization is derived directly from the optical-flow constraints in a variational formulation. Furthermore, our approach provides a new mathematical interpretation of the demons algorithm via fixed-point iterations in a consistent framework.
