Abstract

The invention relates to a method of coding a sequence of pictures using a segment operation of each of the pictures followed by a coding operation of each of the obtained successive partitions, and to a corresponding system. The system includes a projection circuit (11), for estimating on the basis of the mesh defined for a previous picture a projected mesh made of polygons and corresponding to the current picture, a mesh coding circuit (12,13,14,15) for coding motion and texture associated to the projected mesh, and a texture error detection and coding circuit (16,17).
