REGION-BASED TEXTURE CODING 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 new technique relying on a wavelet decomposition of the images, called quincunx bidimensional wavelet transform and adapted to a region-based coding scheme, for applications allowing to reach very low bit rates while keeping a good image quality. Application: multimedia data storage, video and still image transmission.
