Abstract：Considering high complexity of multiple reference frames in Multi-view Video Compression (MVC), a fast coding algorithm for MVC is presented based on the traits of multi-view video. The propose algorithm improves the design of reference-lists in H.264 standard that adapts to traditional video coding, and adjusts the old reference-lists using the temporal and spatial correlations of multi-view video. Additionally, the strategy of mode pre-decision is also used to reduce the computational complexity. The experimental results show that the proposed method can reduce encoding complexity and speed up encoding process effectively. Though the new algorithm is implemented on M-Picture prediction structure, it can be also used in other multi-view video coding structures with multiple reference B-frames.
