Cela s'est traduit par une variation des paramètres des codes et surtout leur application sélective sur des parties significatives de l'image. Dans le cadre de sa normalisation, nous avons montré les performances des codes Reed Solomon et ses limites en cas de variation importante des paramètres et procéder à l'étude comparative avec les turbo codes qui nous a permis d'obtenir une meilleure performance dans une transmission en environnement bruité.Nous avons montré également, qu'il est possible de gérer le mécanisme de la sécurité de la norme avec le tatouage par étalement de spectre en exploitant les propriétés des transformées en ondelettes de JPEG 2000.La robustesse du schéma de ce mécanisme a été montrée face à une attaque comme la compression. 148 pp. Französisch.…
