Abstract: Several implementations relate, for example, to depth encoding and/or filtering for 3D video (3DV) coding formats. A sparse dyadic mode for partitioning macroblocks (MBs) along edges in a depth map is provided as well as techniques for trilateral (or bilateral) filtering of depth maps that may include adaptive selection between filters sensitive to changes in video intensity and/or changes in depth. One implementation partitions a depth picture, and then refines the partitions based on a corresponding image picture. Another implementation filters a portion of a depth picture based on values for a range of pixels in the portion. For a given pixel in the portion that is being filtered, the filter weights a value of a particular pixel in the range by a weight that is based on one or more of location distance, depth difference, and image difference.

Abstract: Several implementations relate to construction of reference picture lists for coding of 3DV content. One or more exemplary embodiments of the present invention include the construction of reference picture lists in accordance with an optimized inter-layer dependency structure. In addition, the reference picture lists may be prioritized according to the degree of redundancy the reference pictures have with respect to the picture for which the reference picture list is constructed. In one implementation, a priority is determined for an inter-layer reference for a picture. The priority is determined relative to one or more other references for the picture. The inter-layer reference is included in an ordered list of references for the picture based on the priority.
