摘要： The invention relates to a method for predicting a movement vector (MVp1) of a partition (P1) of a current image (IN) from a plurality of n reference movement vectors associated respectively with n reference partitions that have been previously encoded and decoded. For a spatial prediction of one such vector, when the geometric shape of the current partition is different from that of k adjacent reference partitions (pr1, pr2, . . . prk), with k≤n, the movement vector of the current image partition is determined from a function of at least one reference movement vector belonging to a set of k reference movement vectors associated respectively with k adjacent reference partitions.

摘要： A method and device relate to coding an image split up into partitions, which comprises the selection of at least one mode of coding and of its associated coding information items, from among items placed in competition, the prediction of the data of a current partition, the determination of residual data. Calculation of the value of a function representative of said residual data are performed, then the comparison of said calculated value with a value selected as value of competition index from among the associated values. If the values are equal, said signal transmitted comprises said residual data and said associated coding information items. If not, the residual data determined are modified so that the value of the function representative of the residual data is equal to the selected value of competition index, the signal transmitted comprising the modified residual data, excluding the selected value of competition index.
