The reference software adopts full search scheme, and the increased computation is in proportion to the number of searched reference frames. However, the reduction of prediction residues is highly dependent on the nature of sequences, not on the number of searched frames. In this paper, we present a method to speed up the matching process for multiple reference frames. For each macroblock, we analyze the available information after intra prediction and motion estimation from previous one frame to determine whether it is necessary to search more frames. The information we use includes selected mode, inter prediction residues, intra prediction residues, and motion vectors. Simulation results show that the proposed algorithm can save up to 90% of unnecessary frames while keeping the average miss rate of optimal frames less than 4%. © 2003 IEEE.Forecasting; Image coding; Motion Picture Experts Group standards; Inter prediction; Intra Prediction; Matching process; Motion Vectors; Multiple-reference frames; Reference frame; Reference software; Video coding standard; Motion estimationconference paper10.1109/ICASSP.2003.11991282-s2.0-84881071928
