Abstract (en)
[origin: WO2011001078A1] 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.
