Abstract
A method for estimation of global error motion vectors, which represent unwanted global picture instabilities in a picture sequence in digital video signals. The method uses a motion vector estimator with an adaptively variable measuring time distance, as well as spatial processing and temporal processing, in order to estimate a sequence of global motion vectors, from which a sequence of global error motion vectors is separated in order to allow stabilization of a picture sequence in digital video signals.
