摘要： A method of coding at least one image comprising the steps of splitting the image into a plurality of blocks, of grouping said blocks into a predetermined number of subsets of blocks, of coding each of said subsets of blocks in parallel, the blocks of a subset considered being coded according to a predetermined sequential order of traversal. The coding step comprises, for a current block of a subset considered, the sub-step of predictive coding of said current block with respect to at least one previously coded and decoded block, and the sub-step of entropy coding of said current block on the basis of at least one probability of appearance of a symbol.

摘要： A system and methods for a CODEC driving a real-time light field display for multi-dimensional video streaming, interactive gaming and other light field display applications is provided applying a layered scene decomposition strategy. Multi-dimensional scene data is divided into a plurality of data layers of increasing depths as the distance between a given layer and the plane of the display increases. Data layers are sampled using a plenoptic sampling scheme and rendered using hybrid rendering, such as perspective and oblique rendering, to encode light fields corresponding to each data layer. The resulting compressed, (layered) core representation of the multi-dimensional scene data is produced at predictable rates, reconstructed and merged at the light field display in real-time by applying view synthesis protocols, including edge adaptive interpolation, to reconstruct pixel arrays in stages (e.g. columns then rows) from reference elemental images.

摘要： The present invention provides an image processing apparatus and method destined for processing image data sent via a communication system. In the apparatus and method, image data corresponding to designation data supplied from the user are coupled to each other for grouping, features of the image data corresponding to the designation data, and the image data once coupled together as in the above are uncoupled according to the features of the grouped image data, to thereby accurately localize an area the user is interested in. Also, according to the present invention, a time interval between the designation data is computed, and the image data are coupled to each other when the computed time interval is less than a predetermined threshold, while they are not coupled to each other when the computed time interval exceeds the predetermined threshold, thereby detecting when the user's interest shifts to another image area. With this detection of the shift of the user's interest, it is possible to accurately localize an area the user is interested in.
