Abstract :
The authors discuss with the development of a coding system able to reach high compressions of picture data, without notable distortion, by integrating vector quantization and polynomial approximation. The whole process is driven by the latter, while the former is used in textured areas only. The polynomial approximation module is described in depth, together with its integration with the other module. Results obtained on standard images are presented and discussed
