The invention relates to a method of representing a sequence of pictures which are grouped into sets comprising at least two successive pictures, known as groups of pictures (GOP), whereby a textured, meshed three-dimensional model is associated with each of said GOPs. According to the invention, the three-dimensional model associated with the n level GOP is represented with an irregular mesh taking account of at least one vertex of at least the irregular mesh representing the three-dimensional model that is associated with the n-1 level GOP, said vertex being known as the common vertex.
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 sommet commun.
