Second generation video coding schemes and their role in mpeg-4
Luis Miguel Torres, M. Kunt, Fernando M. B. Pereira · 1996
Since its introduction in 1985, there has been a lot of activity in the field of second generation still image coding. In the last years, the approach has been extended to video coding and has been the basis for European RACE research projects. The objective of this paper is to summarize the main concepts underlying second generation video coding and to present the approach taken in the RACE project MORPHECO in the context of segmentation-based video coding schemes. Comments and results on the evolution of the system, in the framework of the MPEG-4 SESAME proposal presented on behalf of the RACE project MAVT are also outlined. In order to have a more complete paper, current state of the art in MPEG-4 activities are also summarized 1 . The paper ends with conclusions and new trends in the field. A basic introduction to the main characteristics and limitations of first generation coding will be also presented in order to have a self-contained paper. A more complete description of secon...
