Error concealment for arbitrarily shaped video objects
Michael R. Frater, W.S. Lee, Mark R. Pickering, J.F. Arnold · 2002
Trends in video coding technology have included the coding of arbitrarily shaped objects and the improvement of the robustness of video bitstreams when subjected to errors during transmission. In this paper, we examine the interaction of these two technologies, using a coder and decoder based on MPEG 4-video. Effective techniques are proposed for concealing the effects of transmission errors.
