    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: 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 process for coding an image of a view from among a plurality of views, including the following steps: selecting a first or a second coding method to code image data from the image; generating a data signal containing information indicating whether it is the first or the second coding method that has been selected, and, if it is the first coding method, coding the original image data so as to provide coded original data, and, if it is the second coding method, coding processed image data from the image obtained by image processing of the original image data so as to provide coded processed data; and coding information describing the image processing which has been applied.
