摘要： Techniques for image rendering are described herein. The techniques may include providing image data to an encoder for transmission to a display. An indication of whether at least a portion of the image data is video data or non-video data is provided. A first policy may be implemented for image data that is video data. The first policy prioritizes transmission of the image data over encoding image quality. A second policy may be implemented for image data that is non-video data. The second policy prioritizes encoded image quality over transmission of the encoded images.

摘要： The techniques introduced here include a system and method for transcoding multimedia content based on the results of content analysis. The determination of specific transcoding parameters, used for transcoding multimedia content, can be performed by utilizing the results of content analysis of the multimedia content. One of the results of the content analysis is the determination of image type of any images included in the multimedia content. The content analysis uses one or more of several techniques, including analyzing content metadata, examining colors of contiguous pixels in the content, using histogram analysis, using compression distortion analysis, analyzing image edges, or examining user provided inputs. Transcoding the multimedia content can include adapting the content to the constraints in delivery and display, processing and storage of user computing devices.

摘要： Three-dimensional data is compressed at a high compression ratio without deteriorating resolution and accuracy, by computing a coupling coefficient from input three-dimensional data and a three-dimensional base data group obtained from a plurality of objects and outputting the coupling coefficient as compressed data. Specifically, the three-dimensional data is input to corresponding point determination means. The corresponding point determination means generates three-dimensional data to be synthesized in which vertexes of the three-dimensional data are made to correspond to vertexes of three-dimensional reference data serving as a reference to determine association relationship between vertexes. Coefficient computation means computes a coupling coefficient for coupling a three-dimensional base data group used for synthesis of three-dimensional data to synthesize three-dimensional data to be synthesized, and outputs the computed coupling coefficient as the compressed data of the three-dimensional data.

摘要： Multiview videos are acquired by overlapping cameras. Side information is used to synthesize multiview videos. A reference picture list is maintained for current frames of the multiview videos, the reference picture indexes temporal reference pictures and spatial reference pictures of the acquired multiview videos and the synthesized reference pictures of the synthesized multiview video. Each current frame of the multiview videos is predicted according to reference pictures indexed by the associated reference picture list with a skip mode and a direct mode, whereby the side information is inferred from the synthesized reference picture. Alternatively, the depth images corresponding to the multiview videos of the input data, and this data are encoded as part of the bitstream depending on a SKIP type.
