| Abstract(in English) | This paper describes a motion estimation method for H.264 based on RDO (Rate-Distortion Optimization). RDO have not been adopted for motion estimation, because calculation of RD cost, which consists of accurate bits and distortion gotten from encoding and decoding, incurs considerable computation cost. In the proposed method, high precision motion estimation with practical computation cost can be attained by only applying RDO to sub-pixel motion estimation. In software simulation results for several video sequence, the proposed method can achieve about 1.71%～3.11% bit reduction in compared with conventional SAD based approaches. |
