摘要： The invention relates to a method for coding an image data macroblock of a sequence of images presented in the form of a base layer and at least one enhancement layer. The image data macroblock to which corresponds an image data block in the base layer, called a corresponding block, belongs to the enhancement layer. The method comprises the following steps: generate, for the said image data macroblock, a prediction macroblock of image data from one block or several blocks of image data blocks of the said base layer previously coded and reconstructed, generate a macroblock of residues from the prediction macroblock and from the image data macroblock MBEL of the enhancement layer, and code the said macroblock of residues. According to the invention, the image data blocks of the said base layer are different from the corresponding block.

摘要： The invention relates to a process for coding images transmitted according to the so-called multiresolution technique. According to this process, a step of pixel level processing of so-called mixed blocks of pixels, that is to say those shared between at least one zone of a first resolution and at least one zone of a second resolution, is preformed. A block is thus transmitted, the pixels of whose zone of the first resolution are assigned this first resolution and the pixels of whose zone of second resolution are assigned this second resolution.

A method for reconstructing a current block of an image is described, the current block being encoded using predictive encoding of segments resulting from geometry adaptive block partitioning of said current block. After decoding encoded data comprising at least one flag and motion vectors, wherein blocks referenced by the motion vectors are used for prediction of segments of the current block, the at least one flag and an encoding order of the motion vectors in the encoded data is used for determining which of the referenced blocks exhibits a geometry that matches the geometry of the current block and for determining a segment of the determined block, wherein prior to determining the segment, the determined block is geometry adaptive block partitioned into segments from which the segment is determined for predicting one of the segments of the current block.
