Abstract

When macroblocks are lost in an MPEG decoder, the decoder can try to conceal the error by estimating the missing area. Many different methods for this type of concealment have been proposed. In previous work, we showed how the use of a decision tree adaptively choosing among several different error concealment methods can outperform each single method. In this paper, we improve the decision tree approach, and compare it against the use of concealment motion vectors
