Abstract

This paper presents a high efficiency method to decide the inter mode of the H.264/AVC encoder. Although rate-distortion optimization (RDO) improving the video quality in video compression largely, its high computational complexity brings huge time cost. The key idea of this paper is to reduce the candidate modes by the underlying relation between motions and macroblock partition types. Thus, a motion vector related evaluation approach with adaptive multilevel thresholds has been proposed together with SKIP mode early determination strategy. The simulation results show that the proposed method achieves 33.4% time reduction in average with about 0.06db PSNR loss and 1.45% bit-rate increase.
