摘要：
A study oil tile use of vector rational interpolation for tile estimation of lost or erroneously received motion vectors of MPEG-2 coded video bitstreams for error concealment purposes is reported. Four different nonlinear interpolation schemes are examined. They are capable of adapting their behaviour to neighbouring motion information. Simulation results prove the success of their application to concealment of predictively coded frames. Such concealment is fast and thus adequate for real-time applications.
