    • The invention relates to a method for coding a current block of a sequence of images comprising the following steps: - determining (20, 30) at least one candidate motion vector associated with a neighbouring block of said current block, - determining (24, 34) a prediction motion vector from the candidate motion vector, and - coding (26, 36) the current block from the prediction motion vector. Advantageously, the prediction motion vector is determined according to the following steps: - determining (22, 32), for the candidate motion vector, a corrective motion vector so as to minimise a distortion calculated between the neighbouring block successively coded and reconstructed and a prediction block motion compensated by the at least one candidate motion vector modified by the corrective motion vector, and - determining (24, 34) the prediction motion vector from the candidate motion vector modified by the corrective motion vector.
    • 本发明涉及一种用于编码图像序列的当前块的方法,包括以下步骤: - 确定(20,30)与所述当前块的相邻块相关联的至少一个候选运动矢量, - 确定(24,34) )来自候选运动矢量的预测运动矢量,以及从预测运动矢量编码(26,36)当前块。 有利地,根据以下步骤确定预测运动矢量: - 对于候选运动矢量确定(22,32)校正运动矢量,以便最小化在连续编码和重建的相邻块之间计算的失真和预测 通过由所述校正运动矢量修改的所述至少一个候选运动矢量补偿的块运动;以及 - 从由所述校正运动矢量修改的所述候选运动矢量确定(24,34)所述预测运动矢量。
