Non Uniform Multiresolution Method for Optical Flow Computation

Abstract : In this paper we propose a non uniform multiresolution method defining a new approach for coarse to fine grid generation. It allows to locally increase the resolution of the grid according to the studied problem. Each added node refines the grid in a region of interest and increases the numerical accuracy of the solution in this region. We make use of such a method for solving the optical flow equation with a non quadratic regularization scheme allowing the computation of optical flow field while preserving its discontinuities. This new scheme is used for processing oceanographic and atmospheric image sequences.
