摘要： The method includes segmentation of the video image into image blocks, movement estimation per image block in order to obtain a field of movement vectors. It is characterized in that it includes a stage of reassignment of a vector to a block by selecting one movement vector from among N predominant vectors belonging to the field of vectors. The applications relate to movement estimation, for example, by image-block matching.

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： A method for dual-standard coding of very low data-rate images and a coder-decoder system for implementing the method, wherein images can be transmitted with low spatial "Quarter of Common Intermediate Format" (QCIF) resolution and with high time resolution according to a first standard, or with high spatial "Common Intermediate Format" (CIF) resolution and low time resolution according to a second standard. In the method and system, the coding of the images includes calculating the mean value of the quantification steps used by a quantifier circuit, comparing the calculated mean value with a first predetermined threshold value and with a second predetermined threshold value higher than the first threshold value, and, chronologically, coding the images in the first standard when the mean value of the quantification steps is lower than the first predetermined threshold value, then coding the images in the first standard as long as the mean value of the quantification steps is lower than the second predetermined threshold value, then coding the images in the second standard as long as the mean value of the quantification steps is higher than the second predetermined threshold value, then coding the images in the first standard when the mean value of the quantification steps is lower than the first predetermined threshold value.
