摘要： Various implementations are described. Several implementations relate to video and depth coding. One method includes selecting a component of video information for a picture. A motion vector is determined for the selected video information or for depth information for the picture(1010, 1040). The selected video information is coded based on the determined motion vector (1015). The depth information is coded based on the determined motion vector (1035). An indicator is generated that the selected video information and the depth information are coded based on the determined motion vector (1030, 1050). One or more data structures are generated that collectively include the coded video information, the coded depth information, and the generated indicator (1065, 1070).

摘要： Various implementations are described. Several implementations relate to one or more encoding modes that use depth information to determine a corresponding reference block. According to a general aspect, a portion of a first-view image from a first view in a multiple-view system is encoded. The portion is all or part of the first-view image. It is determined that a portion of a second-view image from a second view in the multiple-view system corresponds to the portion of the first-view image. The determination is based on a second-view depth value providing depth information for the portion of the second-view image. The portion of the second-view image is encoded using information from the encoding of the portion of the first-view image.

摘要： Various implementations are described. Several implementations relate to depth coding. According to a general aspect, prediction mode information is accessed for reconstructing a target block of data from a picture. The prediction mode information indicates that the target block of data was predicted using a target-block prediction mode that was determined based on a neighbor-block prediction mode of a neighbor block. The neighbor block is a spatial neighbor of the target block in the picture. The neighbor-block prediction mode of the neighbor block is determined. The target-block prediction mode of the target block is determined based on the neighbor-block prediction mode. The target block is reconstructed by predicting the target block using the determined target-block prediction mode.

摘要： Various implementations are described. Several implementations relate to determining, providing, or using a depth value representative of an entire coding partition. According to a general aspect, a first portion of an image is encoded using a first-portion motion vector that is associated with the first portion and is not associated with other portions of the image. The first portion has a first size. A first-portion depth value is determined that provides depth information for the entire first portion and not for other portions. A second portion of an image is encoded using a second-portion motion vector that is associated with the second portion and is not associated with other portions of the image. The second portion has a second size that is different from the first size. A second-portion depth value is determined that provides depth information for the entire second portion and not for other portions.

摘要： Implementations are provided that relate, for example, to view tiling in video encoding and decoding. A particular method includes accessing a video picture that includes multiple pictures combined into a single picture (826), accessing information indicating how the multiple pictures in the accessed video picture are combined (806, 808, 822), decoding the video picture to provide a decoded representation of at least one of the multiple pictures (824, 826), and providing the accessed information and the decoded video picture as output (824, 826). Some other implementations format or process the information that indicates how multiple pictures included in a single video picture are combined into the single video picture, and format or process an encoded representation of the combined multiple pictures.

A decoding method comprising the steps of: extracting an indicator representative of an original format for received occlusion data (S702), the original format selected from a one of a sparse occlusion data format and a filled occlusion data format; arranging 2D data, which is associated with said occlusion data, at location after temporal and inter-view pictures in a reference picture list (S1102); identifying at least one of an occlusion area macroblock and a non- occlusion area macroblock for the occlusion data (S1103); decoding said occlusion data to produce decoded occlusion data (S1104, S703), wherein said decoding includes: for each non-occlusion macroblock, when said indicator indicates the filled occlusion data format, replacing the occlusion data in said non-occlusion macroblock with a corresponding macroblock of associated 2D data to produce a decoded occlusion data; and when said indicator indicates the sparse occlusion data format, filling said non- occlusion macroblock with data indicative of a defined characteristic to produce decoded occlusion data; and otherwise for each occlusion macroblock, decoding said occlusion macroblock to produce decoded occlusion data; and outputting the decoded occlusion data (S1105, S705).

摘要： Various implementations are described. Several implementations relate to joint depth estimation for multiple depth maps. In one implementation, a first-view depth indicator for a location in a first view is estimated, and a second-view depth indicator for a corresponding location in a second view is estimated. The estimating of one or more of the first-view depth indicator and the second-view depth indicator is based on a constraint. The constraint provides a relationship between the first-view depth indicator and the second-view depth indicator for corresponding locations.
