摘要： 3D video coding/decoding supporting inter-component prediction is made operatable with respect to a broader range of settings with respect to accompanying individual views with depth and deactivation/enablement of inter-component prediction, by using one or more flags in the data stream to control the enablement/disablement of the availability of inter-component prediction for coding units of a current picture.

摘要： The way of predicting a current block by assigning constant partition values to the partitions of a bi-partitioning of a block is quite effective, especially in case of coding sample arrays such as depth/disparity maps where the content of these sample arrays is mostly composed of plateaus or simple connected regions of similar value separated from each other by steep edges. The transmission of such constant partition values would, however, still need a considerable amount of side information which should be avoided. This side information rate may be further reduced if mean values of values of neighboring samples associated or adjoining the respective partitions are used as predictors for the constant partition values.

摘要： Although wedgelet-based partitioning seems to represent a better tradeoff between side information rate on the one hand and achievable variety in partitioning possibilities on the other hand, compared to contour partitioning, the ability to alleviate the constraints of the partitioning to the extent that the partitions have to be wedgelet partitions, enables applying relatively uncomplex statistical analysis onto overlaid spatially sampled texture information in order to derive a good predictor for the bi-segmentation in a depth/disparity map. Thus, in accordance with a first aspect it is exactly the increase of the freedom which alleviates the signaling overhead provided that co-located texture information in form of a picture is present. Another aspect pertains the possibility to save side information rate involved with signaling a respective coding mode supporting irregular partitioning.
摘要翻译：尽管基于楔形的划分似乎代表了一方面在侧面信息速率和另一方面可实现的分割可能性之间的更好的权衡，与轮廓划分相比，能够将分区的约束减轻到分区的程度必须是楔形分区，使得能够对覆盖的空间采样纹理信息应用相对不复杂的统计分析，以便为深度/视差图中的双分割导出良好的预测器。因此，根据第一方面，如果存在图像形式的共位纹理信息，那么正是自由度的增加而减轻信令开销。另一方面涉及节省支持不规则分区的相应编码模式的相关信息速率的可能性。

摘要： A higher compression rate or better rate/distortion ratio is achieved by adopting or predicting second coding parameters used for encoding a second view of the multi-view signal from first coding parameters used in encoding a first view of the multi-view signal. The redundancies between views of a multi-view signal were found to be not restricted to the views themselves, such as the video information thereof. Rather, the coding parameters in parallely encoding these views show similarities which may be exploited in order to further improve the coding rate.
