Abstract

The huge increase of the communication services has suggested to investigate new algorithmic avenues to solve the perpetual rate/distortion trade-off in video coding applications. The problem is drawn nowadays according to very severe constraints: bit-rate budgets become smaller and domestic communication networks at 8 Kbit/s. Two approaches are explored. The first consists of extending the standards already developed in image communication by successive improvements and alternatives inside the algorithmic frameworks. The second proposes a complete change of the basic tools and a design of hybrid schemes by introducing some new methodological techniques which have been already validated by the Computer vision community but never introduced, for compatibility or complexity reasons, into the encoding strategies. This tutorial paper presents these different issues and evokes their advantages. Some experiments performed in our laboratory to encode efficiently time-varying image sequences are eventually presented.
