摘要： The invention relates to a method and device for encoding a video image sequence by motion-compensated temporal filtering with the aid of a digital wavelet decomposition (110), wherein said digital wavelet decomposition consists in dividing the video image sequence into image groups and in determining (112, 113, 114, 115) the representative image of a group called a destination group on the basis of at least one image composed of pixels of the image group called a source group. Said invention is characterised in that the representative image comprises pixels and sub-pixels which are determined on the basis of pixels and sub-pixels obtainable by sampling (110, 111) of at least one image of the source group. A decoding method and associated decoders are also disclosed.

摘要： The invention relates to a technique for encoding image data, and to a corresponding decoding technique. The invention comprises implementing a prediction of data of a current block (2) based on at least one already encoded block (1, 6) or reference block, wherein said prediction step takes into account a set of encoded blocks adjacent to said current block and including blocks that have not yet been considered according to said writing path order. The encoding includes the steps of: generating a dependence tree associating a current block with at least one reference block from which the predicted block associated with the current block has been predetermined; and inserting information representative of said dependence tree into said set of data associated with each block.
