Paper Abstract

This paper proposed a linear rate-distortion (RD) cost model for skip mode in H.264/MPEG-4 AVC. The proposed RD cost model is derived theoretically based on the quantization scheme of H.264, and the simulation results also verify that the proposed RD cost model can estimate the RD cost of skip mode accurately. Based on the proposed RD cost model, an early skip mode selection algorithm is provided. The proposed early skip mode selection method can terminate the mode selection process adaptively and works well for both low complexity and high complexity video. Experimental results show that the proposed early skip mode selection algorithm can save the encoding time up to 56% with negligible performance loss compared with the original reference encoder.
