Abstract :
In this paper, we present a solution for the phase unwrapping problem using a Markovian modelization. The computational cost of this approach being particularly heavy in phase unwrapping, we propose to utilize a multigrid technique. An adaptative model is proposed in order to allow discontinuities in the unwrapped phase image. Results are presented on a real interferogram
