Abstract

"MéTODO PARA REPRESENTAR UMA SEQüêNCIA DE IMAGENS UTILIZANDO MODELOS 3D, E SINAL E DISPOSITIVOS CORRESPONDENTES". A invenção refere-se a um método de representar uma seqüência de imagens que são agrupadas em conjuntos compreendendo pelo menos duas imagens sucessivas, conhecidos como grupos de imagens (GOP), pelo que um modelo tridimensional de malha, de textura é associado a cada um dos referidos GOPs. De acordo com a invenção, o modelo tridimensional associado ano GOP de nível n é representado com uma malha irregular levando em consideração pelo menos um vértice pelo menos da malha irregular representando o modelo tridimensional que é associado ao GOP de nível n-1, o referido vértice sendo conhecido como o vértice comum."METHOD FOR REPRESENTING A SEQUENCE OF IMAGES USING 3D MODELS, AND SIGNAL AND CORRESPONDING DEVICES". The invention relates to a method of representing a sequence of images that are grouped into sets comprising at least two successive images, known as image groups (GOP), whereby a three-dimensional textured mesh model is associated with each other. of those GOPs. According to the invention, the n-level GOP-associated three-dimensional model is represented with an irregular mesh taking into account at least one vertex of the irregular mesh representing the three-dimensional model which is associated with the n-1 level GOP, said vertex being known as the common vertex.
