中文摘要:

可变尺寸运动评价(我) 并且不同评价(DE ) 被采用在当前的联合 multiview 录像模型(JMVM ) 为每 macroblock (MB ) 选择最好的编码模式。这种技术完成最高可能的编码效率,但是它导致从实际申请妨碍编码的 multiview 录像(MVC ) 的极其大的计算复杂性。这篇论文为 MVC 建议快模式决定算法的适应早结束。早终止模式决定过程基于会见关联在邻居看法使用相应 MB 的编码信息。建议快模式决定算法能完成的试验性的结果表演计算 50% 计算没有率失真(RD ) 的重要损失节省性能。

英文摘要:

Variable size motion estimation (ME) and disparity estimation (DE) are employed to select the best coding mode for each macroblock (MB) in the current joint multiview video model (JMVM). This technique achieves the highest possible coding efficiency, but it results in extremely large computation complexity which obstructs the multiview video coding (MVC) from practical application. This paper proposes an adaptive early termination of fast mode decision algorithm for MVC. It makes use of the coding information of the corresponding MBs in neighbor view based on inter-view correlation to early terminate the mode decision procedure. Experimental results show that the proposed fast mode decision algorithm can achieve computational 50% computation saving with no significant loss of rate distortion (RD) performance.
