Abstract:
A method for coding a sequence of video images comprising a cutting into zones of at least one current image of the sequence, characterized in that, for the coding of at least one target zone of said at least one current image, it comprises the steps of: determination (E2) of a set of candidate zones in previously coded and then decoded parts of images of the sequence, minimizing a prediction error calculated over the neighborhood of the target zone, formation (E3) of a set of groups of candidate zones in said set of candidate zones, as a function of a criterion of similarity between the candidate zones, identification (E6) of a best group in said set of groups, minimizing a reconstruction error with respect to the target zone, determination (E6) of an indication (n) representative of said identified best group; and coding (E7) of said indication (n).
