Abstract

In this paper, early-stop and Motion Vector (MV) re-use approaches are proposed for the MPEG-2 to H.264 transcoding to reduce the computation of the variable block-size motion estimation. By combining the two approaches, the number of MV search points is reduced by more than 80% without significantly affecting the video quality. The proposed approaches can also be used in fast variable block-size motion estimation for the H.264 video encoding.
