PROCÉDÉ ET APPAREIL POUR CODER OU DÉCODER UNE IMAGE AVEC UNE PRÉDICTION D'INFORMATIONS DE MOUVEMENT INTER-COUCHE SELON UN SYSTÈME DE COMPRESSION D'INFORMATIONS DE MOUVEMENT

摘要

The invention concerns a method, device, and computer program for motion vector prediction in scalable video encoder and decoder.It concerns the process to determine motion information predictor in the enhancement layer of a scalable encoding scheme also known as motion derivation process. It comprises a correction of the position in the reference layer used to pick-up the more relevant motion information available due to the compression scheme. Accordingly, motion information prediction is improved.
