REGION-BASED TEXTURE CODING METHOD AND DECODING METHOD, AND CORRESPONDING SYSTEMS

摘要

The invention relates to an image sequence coding method in which images are segmented and coded with respect to their contours and textures. The texture coding step is carried out by means of a lattice vector quantization method adapted to region-based coding schemes where regions have arbitrary shapes, for applications allowing to reach very low bit rates while keeping a good image quality.
