              <p>Le nouveau standard multimédia Mpeg-4 traite aussi bien des aspects compression que de fonctionalités de haut niveau telles que la manipulation d'objets. La méthode LAR offre un cadre unique permettant une compression efficace tout en offrant une segmantation à coût "quasi-nul" à travers le principe de représentation en régions auto-extractibles. Aussi montrons nous ici que notre méthode peut constituer une alternative au mode classique de codage intra de Mpeg-4. En particulier, l'approche réussi à unifier le codage de la forme et de la texture d'un VOP.</p>
