摘要: A method for coding a video sequence is provided that includes encoding a portion of a picture in the video sequence in lossless coding mode, and signaling a lossless coding indicator in a compressed bit stream, wherein the lossless coding indicator corresponds to the portion of a picture and indicates whether or not the portion of the picture is losslessly coded. A method for decoding a compressed video bit stream is provided that includes determining that lossless coding mode is enabled, decoding a lossless coding indicator from the compressed video bit stream, wherein the lossless coding indicator corresponds to a portion of a picture in the compressed video bit stream and indicates whether or not the portion of the picture is losslessly coded, and decoding the portion of the picture in lossless coding mode when the lossless coding indicator indicates the portion of the picture is losslessly coded.

摘要: An apparatus for remote processing of raw image data receives the raw image data from a camera, such as a security camera. The apparatus includes a detection module to detect portions of the image data that contain possible regions of interest. Information indicating the portions that contain the possible regions of interest is then used during a compression process so that the portions that contain the possible regions of interest are compressed using one or more compression algorithms to facilitate further analysis and the remainder are treated differently. The compressed image data is then transmitted to a central system for decompression and further analysis. In some cases, the detection system may detect possible regions of interest which appear to be faces, but without performing full facial recognition. These parts of the image data are then compressed in such a way as to maintain as much facial detail as possible, so as to facilitate the facial recognition when it is carried out at the central server. The detection may be performed on the raw image data or may be performed as part of the compression process after a transformation of the raw image data has been carried out.

摘要: Methods, apparatus, systems for video processing, including video encoding or video decoding are described. One example method includes performing a conversion between a video including a video picture that includes one or more subpictures and a bitstream of the video. The bitstream conforms to a format rule specifying that a first syntax element indicating whether an operation is performed across a boundary of a subpicture in the coded layer video sequence is selectively included responsive to a number of subpictures in the video picture.

摘要: Systems and methods are provided for using a Multi Focal Plane (MFP) prediction in predictive coding. The system detects a camera viewpoint change between a current frame from a current camera viewpoint to a previous frame from a previous camera viewpoint, decomposes a reconstructed previous frame to a plurality of focal planes, adjusts the plurality of focal planes from the previous camera viewpoint to correspond with the current camera viewpoint, generates an MFP prediction by summing pixel values of the adjusted plurality of focal planes along a plurality of optical axes from the current camera viewpoint, determines an MFP prediction error between the MFP prediction and the current frame, quantizes and codes the MFP prediction error, and transmits, to a receiver over a communication network, the camera viewpoint change and the coded quantized MFP prediction error for reconstruction of the current frame and display of the 3D scene.

摘要: A decoding method is disclosed that comprises: determining whether a current block of a picture extends beyond a boundary of the picture; determining for each split mode of a plurality of split modes whether said current block is allowed to undergo splitting according to said split mode by checking whether at least one of the split line is co-located with one of the picture border or whether the size of the block part inside the picture along the picture boundary is a multiple of a minimum block size; decoding from a bitstream a current split mode of the current block responsive to the allowed split modes; and decoding the current block according to the current split mode.

摘要: A method of video processing includes performing a conversion between a video unit of a video and a coded representation of the video using at least a video picture. Only one of a sub-picture coding mode or a resolution-changing coding mode is enabled for the video unit. The sub-picture coding mode is a mode in which the video picture is divided into multiple sub-pictures, and the resolution-changing coding mode is a mode in which a resolution of the video picture is adjusted during the conversion.

摘要: Methods, apparatus, systems for performing video processing such as video encoding, video decoding or video transcoding are described. One example method of video processing includes performing a conversion between a video comprising one or more video layers and a bitstream of the video according to a rule. The rule specifies that responsive to a value of a first field in a sequence parameter set (SPS) that is referred to by a video layer, a second field in a video parameter set referred to by the SPS that is indicative of a maximum number of sublayers allowed in the bitstream is construed to be equal to a third field in the SPS. The third field is indicative of a maximum number of sublayers allowed in the video layer.
