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.

摘要： The invention relates to a method for encoding an image sequence, including the step of cutting a reference image (Iref) into blocks and a prediction step that includes the following steps: determining (121) monitoring vectors associated with a common image and cutting (122) the same into sub-blocks defining a first partition; determining (131) monitoring vectors associated with an image to be compensated and cutting (132) the same into sub-blocks defining a first partition obtaining a common partitioning (141) into basic sub-blocks; determining (123, 133) first and second sets of monitoring vectors for the basic sub-blocks; movement-compensating a sub-block of the image to be compensated towards a sub-block of the common image.

摘要： The invention relates to a method for encoding a sequence of images generating a data stream in the form of a structure of embedded data layers of n successive levels each of which corresponds to the predetermined resolution of said images. Said method comprises an encoding stage consisting in encoding at least one of said layers of an n+1 level by prediction on the basis of said level n layer and in encoding each data layer of the level n in the form of a base sub-stream and, optionally, in the form of at least one enhancement sub-stream enabling to obtain at least one version of the enhanced quality of said images. The inventive method also consists in encoding, for at least one data layer of the n level, at least one single sub-stream enabling to reconstruct the version of said images at said level n resolution with a quality higher than said enhanced qualities, wherein said single sub-steam of the level n layer is not used during the prediction encoding of the layers of a level other than the level n.

摘要： The invention relates to a method of encoding a source image sequence. The inventive method comprises: motion/texture decomposition, such as to produce, for at least some of the source images, information that is representative of motion, known as motion images, and information that is representative texture, known as texture images; and wavelet encoding, said encoding being applied to difference images (residue) which are obtained by comparing a motion image, or texture image respectively, with a corresponding estimated image.

摘要： The invention relates to a method for encoding an image or image sequence generating a data flow including data representative of pixel groups, or blocks, in one of said images (IE). The method comprises the steps of: grouping (C1) the blocks in a block cluster based on the proximity of their respective values corresponding to at least one parameter of a block to be encoded; determining (C2) a value of said parameter, said value being characteristic of said block cluster; encoding (C3) blocks of said cluster, wherein the values of said blocks for said parameter are implicitly encoded by inheritance of said characteristic value, or are encoded as refinements relative to said characteristic value, and encoding a data structure associated with said block cluster, said data structure including a piece of data associated with said characteristic value.

摘要： The invention concerns a method which consists in analyzing a field of motion of images, estimated by using a first mesh, to detect a faulty area in the first mesh, and in locating a rupture line in said area; then generating a second mesh including a faultless part consisting of meshes of the first mesh outside the faulty area and two sub-meshes which overlap in a region including the rupture line. Each of the two sub-meshes includes respective meshes delimited by nodes including nodes shared with the faultless part, located at the boundary of the faulty area, and additional nodes not belonging to the faultless part, the rupture line being located between the respective nodes of the two sub-meshes shared with the faultless part. Said second mesh is used to finally estimate the field of motion in the group of images concerned.
