摘要:
A method for coding a block of pixels is described. The coding method comprises: determining a prediction block for the pixel block from a motion vector; calculating a residue between the pixel block and the prediction block; and code the residue. The determination of the prediction block comprises the following steps: determining an intermediate prediction block of size strictly greater than the size of the pixel block; transforming the intermediate prediction block into a first block transformed with a first transform; and transforming the first transformed block into a second block transformed with a second transform of inverse the first transform whose basis functions are shifted by at least a part of each component of the motion vector, the prediction block being extracted from the second transformed block.
