Abstract

In H.264/AVC, simplified rate distortion optimisation (RDO) is performed to estimate the motion vector (MV). As a result, the estimated MV is often suboptimal since the residual bitrate is not considered, which results in the deterioration of the coding efficiency. In this paper, we propose an MV refinement algorithm in which the final MV is selected from a set of candidate MVs by using the RDO including the residual bitrate. To further improve the performance of optimal MV selection, the RD calculation method in the RDO is modified using the deblocking filters. Experimental results show that the proposed algorithm outperforms the conventional H.264 in terms of coding efficiency.
