Abstract
The combined use of bilinear and vector rational interpolation for motion field estimation of erroneously received MPEG-2 video bitstreams is reported. Motion vector rational interpolation is capable of adapting its behaviour with respect to neighbouring motion information. Bilinear interpolation, operating on a finer interpolation grid, takes neighbouring spatial correlations into account. Thus, the combined method is expected to lead to improved motion estimates of the lost motion data and thus satisfactory concealment. It additionally proves to be adequately fast for real-time applications (MPEG-2 decoder). Simulation results prove the efficiency of the method compared to similar approaches.
