| 摘要 |
The invention relates to the decoding of a data signal representative of at least one current image (IN) split into partitions, said method comprising, for at least one current partition (B) to be reconstructed in said image, the steps of predicting (D3) said current partition on the basis of at least one already decoded causal partition, then reconstructing (D4) said current partition on the basis of said predicted current partition, delivering a reconstructed current partition (B). There is moreover carried out the determination (D5) of at least one already decoded causal partition (B*) with the aid of a motion estimation applied to said reconstructed current partition, then the modification (D6) of said reconstructed current partition by calculation of a function applied both to said determined causal partition (B*) and to said reconstructed current partition, delivering a modified reconstructed current partition (B). A corresponding coding of at least one image (IN) split into partitions is also implemented. |
