Abstract

L'invention concerne un procédé de représentation d'une séquence d'images regroupées en ensembles d'au moins deux images successives, appelés GOPs, un modèle tridimensionnel maillé texturé étant associé à chacun desdits GOPs. Selon l'invention, le modèle tridimensionnel associé au GOP de niveau n est représenté à l'aide d'un maillage irrégulier tenant compte d'au moins un sommet d'au moins le maillage irrégulier représentant le modèle tridimensionnel associé au GOP de niveau n-1, ledit sommet étant appelé somm et commun.
