    In this paper, we propose a novel optimized motion estimation algorithm with a modified search center for spatial scalability when using inter-layer motion prediction of H.264/SVC. Firstly, up-sampled motion vector of base layer is evaluated to find the relation with the enhancement layer. Based on the results, in enhancement layer encoding we use the motion vector of the base layer to estimate the optimal search center for enhancement layer. Then, based on the modified search center we adaptively control the search range to reduce the redundant motion estimation. The proposed algorithm is evaluated using reference software JSVM. The simulation results show that the proposed algorithm can achieve over 80% computation complexity reduction of total motion estimation.
