Abstract:
To code a video sequence, the similarity is calculated (10) between a block of pixels to code of a current image of the sequence and blocks of pixels of a reference image and at least one motion vector per block of the sequence is determined on the basis of at least one similarity value calculated previously. Furthermore, for at least one block of pixels to code, a prediction (16) is determined of at least one motion vector from neighboring motion vectors that have already been calculated; a final motion vector is determined (18) from similarity values calculated previously for the block to code and on the basis of the predicted motion vector; and the block to code is coded (20) using the final motion vector.
