A method is provided for encoding a portion of a current image, including: an estimation of motion between the current image portion and a plurality of candidate image portions in order to form motion components, an evaluation of a performance criterion for each candidate image portion, and the selection of a reference image portion using said performance criteria. In the method, for at least one motion component, the motion estimation, the performance criteria evaluation and the reference image portion selection only use information considered to be available at the decoder and no motion information is inserted into an output flow intended for a decoder. A corresponding decoding method is also provided. |
