How to Construct an MPEG4 API: A Videoconference Application Example

L. Peyronny, O. Soligon, C. Roux, O. Avaro, T. Blu

Proceedings of the International Conference on Image and Multidimensional Digital Signal Processing (IMDSP '98), Alpbach , Republic of Austria, July 16, 1998, pp. 111-114.


The construction and animation of face-objects in MPEG-4/SNHC (synthetic natural hybrid coding) systems implies content-based and semantic analysis of the observed 3D scene. These processes require sophisticated image processing tools and algorithms which are time-consuming and also not so suitable for videoconferencing applications. With regard to the coding process following the MPEG-4 standard, it is shown that 4 possible levels of coding are ready-to-send in an MPEG-4 data stream. The main functionalities sought in the MPEG-4 standard are data scalability, user data interactivity and opening to various kinds of coder schemes. With non-high-order semantic interpretation of the observed scene, it is well-known that it is possible to build and animate a facial 3D model. A transcoding system is then needed to fit to the MPEG-4 data stream format.
