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.

摘要： Several implementations relate to 3D video formats. One or more implementations provide adaptations to MVC and SVC to allow 3D video formats to be used. According to a general aspect, a set of images including video and depth is encoded. The set of images is related according to a particular 3D video format, and are encoded in a manner that exploits redundancy between the set of images. The encoded images are arranged in a bitstream in a particular order, based on the particular 3D video format that relates to the images. The particular order is indicated in the bitstream using signaling information. According to another general aspect, a bitstream is accessed that includes the encoded set of images. The signaling information is also accessed. The set of images is decoded using the signaling information.

摘要： Several implementations relate to 3D video (3DV) coding formats. One implementation encodes multiple pictures that describe different three-dimensional (3D) information for a given view at a given time. Syntax elements are generated that indicate, for the encoded multiple pictures, how the encoded picture fits into a structure that supports 3D processing. The structure defines content types for the multiple pictures. A bitstream is generated that includes the encoded multiple pictures and the syntax elements. The inclusion of the syntax elements provides, at a coded-bitstream level, indications of relationships between the encoded multiple pictures in the structure. The syntax elements also enable efficient inter-layer coding of the 3DV content, thereby reducing the bandwidth used to transmit the 3DV content. Corresponding decoding implementations are also provided. Extraction methods are also provided from extracting pictures of interest from such a 3DV video stream characterized by such a 3D structure.

摘要： Several implementations relate to depth map coding. In one implementation, it is determined that differences between collocated video blocks are small enough to be interchanged. Based on that determination, a depth block corresponding to a first of the video blocks is coded using an indicator that instructs a decoder to use a collocated depth block, corresponding to a second of the video blocks, in place of the depth block. In another implementation, a video signal includes a coding of at least a single indicator that instructs a decoder to decode both a depth block and a corresponding video block using collocated blocks, from other pictures, in place of the depth block and the corresponding video block. In another implementation, the depth block and the corresponding video block are decoded, based on the single indicator, using the collocated blocks in place of the depth block and the corresponding video block.

摘要： Several implementations relate to depth map coding. In one implementation, a depth coding rate, that results from coding one or more portions of a depth map using a particular coding mode, is determined. The depth map can be used to render video for a different view than that of the depth map. A depth map distortion, that results from coding the one or more portions of the depth map using the particular coding mode, is determined. A value of distortion for the rendered video, based on the depth map distortion and on a particular relationship between the depth map distortion and values of distortion for the rendered video, is determined. It is determined whether to use the particular coding mode to code the one or more portions of the depth map, and the determination is based on the value of distortion for the rendered video and the depth coding rate.

摘要： The invention is made in the field of depth or disparity image block encoding and decoding using at least one coding mode. A method for encoding a block of a depth or disparity image is described wherein for each used coding mode at least two encoded blocks are determined. The at least two encoded blocks are determined by encoding the block in full resolution and in at least one down sampled resolution, wherein each encoded block comprises at least one flag indicative of the resolution and the coding mode used in encoding. Then, transmission rate cost and distortion cost are determined for each encoded block. The distortion cost is determined for a full resolution reconstruction of the respective encoded block. Finally,transmission rate/distortion ratio optimization is used for selecting one of the encoded blocks for transmission or storage.

摘要： Various implementations relate to depth map coding. In one method, a depth coding rate and depth distortion are determined for a coding mode. Based on the value of depth distortion, a correlation coefficient is determined between at least a portion of a video picture and a translated version of the video picture. The video picture is one or more of a video picture corresponding to the depth being coded, or a rendered video picture for a different view. A video distortion is determined based on the correlation coefficient, and is used to evaluate the coding mode. Another implementation determines a multiplier, to be used in a rate-distortion cost, based on pixel values from one or more of a video picture from a particular view or a rendered video picture for a different view.
