    摘要: Methods and apparatuses for motion skip mode in multi-view coded video using regional disparity vectors are provided. An image block of a picture corresponding to a view of multi-view video content is encoded by obtaining motion information for the image block based upon disparity information for a first region of plural regions of another picture. The other picture corresponds to another view of the multi-view video content, and each region corresponds to less than an entirety of the other picture. Each region includes multiple image blocks, with each region having been determined based on a similarity among disparity vectors of the multiple image blocks. The disparity information for the first region includes a regional disparity vector determined from the disparity vectors of the multiple image blocks of the first region.

    摘要: There are provided methods and apparatus for adaptive reference filtering of bi-predictive pictures in multi-view coded video. An apparatus includes an encoder (100) for encoding a current picture as a bi-predictive picture. The encoder (100) performs adaptive filtering of at least one reference picture to respectively obtain at least one filtered reference picture, and bi-predictively codes the current picture using the at least one filtered reference picture. The at least one reference picture is a picture wherein at least one sample thereof is used for inter-prediction either of subsequent to the least one sample being applied to an in-loop filter or in an absence of the at least one sample being applied to an in-loop filter. Reference filter coefficients for the adaptive filtering are determined responsive to at least one of luma values and chroma values of pixels grouped based on at least one of depth and disparity and motion.

    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, accessing information indicating how the multiple pictures in the accessed video picture are combined, decoding the video picture to provide a decoded representation of at least one of the multiple pictures, and providing the accessed information and the decoded video picture as output. 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.

    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. The selected video information is coded based on the determined motion vector. The depth information is coded based on the determined motion vector. An indicator is generated that the selected video information and the depth information are coded based on the determined motion vector. One or more data structures are generated that collectively include the coded video information, the coded depth information, and the generated indicator.
