A Convex Lifting Approach to Image Phase Unwrapping

Laurent Condat, Daichi Kitahara, Akira Hirabayashi

Abstract

The nonlinear inverse problem of 2-D phase unwrapping consists in estimating an image, while its pixel values are observed modulo 2π. A variational formulation is considered, which consists in minimizing an energy, convex or not, under the nonconvex data fidelity constraints. We propose a new convex relaxation of this combinatorial problem. It shows similar or better performances than the state of the art.
