Adéquation algorithme - architecture pour le traitement multimédia embarqué

Abstract : This thesis deals with visiophony service implementation feasibility for next generation mobile terminal through an embedded multimedia systems conception methodology. We first set up our research context : 3G networks, mobile terminals, processors for video coding, and also ISO/MPEG and IUT-T coding standards. We then propose a system level conception methodology taking into account embedded constraints like terminal autonomy. We apply it to H.263 video coder. This methodology is built along two levels : algorithmic
(system specification and performance analysis) and architectural (hardware / software partitioning and implementation efficiency analysis). To cope with embedded visiophony constraints, we proposed a new video compression scheme taking advantage of video semantic information, as suggested by MPEG-4 object coding approach. In this way, we both propose an adaptive algorithm for face detection and a new coding scheme for very low bit rate video compression.
