Abstract:
A method of coding an image or a sequence of images generating a flow of data in the form of groups of blocks, at least one group of blocks containing image blocks having a resolution and a quality level of identical quantification, the method including the following steps for the at least one group of blocks, of a) a first coding so that each block of the at least one group of blocks has at least one associated parameter that is given a first value, and b) a second coding for giving the associated parameter for at least one block of the at least one group of blocks a second value, so that for the at least one block, the first and second values given for the parameter can be combined during decoding to provide a value assigned to the parameter.
