Abstract (en)
[origin: WO2009071803A1] The invention relates to a method for encoding a portion of a current image, including: an estimation (10) of motion between the current image portion and a plurality of candidate image portions in order to form motion components, an evaluation (14) of a performance criterion for each candidate image portion, and the selection (16) of a reference image portion using said performance criteria. The method is characterised in that, 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. The invention also relates to the corresponding decoding method.
