Fast integer-pel motion estimation on statistical properties for H.264/AVC

초록

In this paper, we propose fast integer-pel motion estimation for H.264/AVC using the local statistics of the motion vectors of neighboring blocks. Using the motion vectors of neighboring blocks, we define a new function to determine the motion search range, which is refined using the cumulative motion vector difference. In addition, we describe a variable step search motion estimation that is incorporated into the refined motion search range. The experimental results show that the proposed algorithm can reduce computational cost by 96% over fast full search motion estimation and by 12% over EPZS in terms of MET, and by 98% over fast full search motion estimation and 29% over EPZS in terms of search points per block with acceptable loss in coding performance. © 2013 International Information Institute.
