Title
Motion based low complexity algorithm for spatial scalability of H.264/SVC
Abstract
In this paper, we propose an improved low complexity algorithm for spatial scalability of H.264/SVC on the basis of the motions in the sequences. First, verification is performed to confirm the redundancy of the previous motion estimation process of H.264/SVC. Then, based on the evaluation results we propose an improved algorithm for our previous work which only focuses on the complexity reduction of enhancement layer. The proposed algorithm can decrease the computation complexity of the base layer using the features of the hierarchical B-picture structure. The proposed algorithm is evaluated using reference software JSVM. The simulation results show that the proposed algorithm can achieve over 90% computation complexity reduction comparing to the original JSVM algorithm. When it is compared with our previous works and some other previous works, 10% complexity reduction and over 27% time saving have been achieved, respectively.
