摘要： A method for coding a dependent view picture based on a reference picture includes selecting a reference picture from a base view picture list if a metric of intra macroblocks in an evaluated picture is greater than a first threshold, selecting a reference picture from a dependent view picture list if a metric of skipped macroblocks in the evaluated picture is greater than a second threshold, and coding a dependent view picture using the selected reference picture. An application-controlled weighting mechanism may be used if both of the thresholds are not met.

摘要： A method for determining a macroblock (MB) coding mode for a current MB in a dependent view. A window around a co-located MB in a base view is determined, wherein the co-located MB is a MB in the base view having a same location as the current MB in the dependent view. A coding mode complexity value (CMCV) is determined for each MB in the window, wherein the CMCV is based on a coding mode used to encode the MB. Rate distortion optimization (RDO) is performed for the current MB using a reduced number of coding modes if a total CMCV for all MBs in the window is less than a threshold, or using all supported coding modes if the total CMCV for all MBs in the window is greater than the threshold. A coding mode for the current MB is determined based on the RDO results.
摘要翻译：一种用于确定从属视图中的当前MB的宏块（MB）编码模式的方法。确定基本视图中位于同一位置的MB周围的窗口，其中同位置MB是基础视图中的MB，具有与从属视图中的当前MB相同的位置。为窗口中的每个MB确定编码模式复杂度值（CMCV），其中CMCV基于用于编码MB的编码模式。如果窗口中所有MB的总CMCV小于阈值，或者使用所有支持的编码模式，则使用减少数量的编码模式对当前MB执行速率失真优化（RDO），如果所有MB的总CMCV为窗口大于阈值。基于RDO结果确定当前MB的编码模式。
