A method for coding a current block of a sequence of images is disclosed. The method comprises: determining at least one candidate motion vector associated with a neighbouring block of said current block, determining a prediction motion vector from the candidate motion vector, and coding the current block from the prediction motion vector. Advantageously, the prediction motion vector is determined according to the following steps: determining, 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 the prediction motion vector from the candidate motion vector modified by the corrective motion vector.
