Abstract :
This paper proposes a fast inter-layer motion estimation algorithm on spatial scalability for scalable video coding extension of H.264/AVC. In the enhancement layer motion estimation, we utilize the relation between two motion vector predictors from the base layer and the enhancement layer respectively to reduce the number of searches. Additionally, we utilize the mode correlations of temporal direction motion estimation to save more encoding time. The simulation results show that the proposed algorithm can save the computation time up to 67.4% compared with JSVM9.12 with less than 0.0476dB video quality degradation.
