Abstract
Method and device for estimating motion between segmented images, or partitions, composed of a number I regions R.sub.i. For performing the method, this device comprises a stage (41) for initializing parameters which describe the motion of each region R.sub.i, in which one of different motion hypotheses chosen a priori is selected after prediction, computation of the prediction error and selection of the motion hypothesis to which the smallest prediction error corresponds. This stage (41) is followed by a stage (42) for intermediate processing by filtering, and a stage (43) for refining the motion parameters and is looped to the input of the stage (42) for an iterative operation until it ends at a given criterion so as to finally obtain I motion information M.sub.i (t) corresponding to the regions R.sub.i.
