抽象的。已经开发了H. 264/多视点视频编码（MVC）标准以使得能够对三维和多视点视频序列进行高效编码。视图间统计依赖性被利用并且视图间预测被采用以提供更有效的编码;然而，这增加了整体编码复杂度。这里利用运动均匀性来选择性地启用视图间预测，并且降低运动估计（ME）和模式选择过程中的复杂性。这已经通过定义将宏块的运动特性与模式选择和视图间预测过程相关联的情况来实现。当比较所提出的算法的H.264/MVC参考软件和其他最近的工作，实验结果表明，在ME时间显着减少，同时保持类似的率失真性能。
Abstract. The H.264/multiview video coding (MVC) standard has been developed to enable efficient coding for three-dimensional and multiple viewpoint video sequences. The inter-view statistical dependencies are utilized and an inter-view prediction is employed to provide more efficient coding; however, this increases the overall encoding complexity. Motion homogeneity is exploited here to selectively enable inter-view prediction, and to reduce complexity in the motion estimation (ME) and the mode selection processes. This has been accomplished by defining situations that relate macro-blocks’ motion characteristics to the mode selection and the inter-view prediction processes. When comparing the proposed algorithm to the H.264/MVC reference software and other recent work, the experimental results demonstrate a significant reduction in ME time while maintaining similar rate-distortion performance.
