Abstract

An algorithm is described for the joint estimation of motion and disparity vector fields from stereoscopic image sequences. Gibbs-Markov random fields are used to model local interaction processes. Interaction of neighboring motion, disparity vectors across a discontinuity line is prohibited via hidden Markov chains signaling discontinuities in the vector fields. The coherence of motion and disparity vector fields, is exploited by means of the epipolar constraint and the so called `loop constraint'. A simulated annealing algorithm is employed to find the global maximum of the posterior probability.
