摘要：
In this paper new methods for error concealment of shape information are proposed for compressed MPEG-4 bit-streams transmitted over error prone channels. For spatial domain, the proposed approach employs the Bezier curves fitting to approximate and outline the VOP For temporal domain, the proposed approach uses the weighted side matching critenion to reconstruct VOP They get better subjective and objective qualities than previous works.
