Title
Fast Motion Estimation Algorithm For H.264/Mpeg-4 Avc By Using Multiple Reference Frame Skipping Criteria
Abstract
The emerging video coding standard, H.264IMPEG-4 AVC, allows using multiple reference frames for motion estimation to enhance temporal prediction. Exhaustive search requires a lot of computation, which is proportional to the number of searched frames. However, the reduction of prediction residues is highly dependent on the characteristics of video sequences. In many cases, searching more reference frames contributes to nothing but only waste of computation. In this paper, we proposed a novel algorithm to accelerate the motion estimation by using reference frame skipping criteria. We adopted selected macroblock mode, intra/inter macroblock prediction residues, discontinuity of motion vectors, and scene changes in the criteria. By using these criteria, each macroblock can determine whether it is necessary to keep on searching more reference frames after the block matching process in the first reference frame. Simulation results show that the proposed algorithm can save up to 67% of ME computation without noticeable degradation of video quality.
