| 摘要 |
The invention relates to encoding a video sequence. A method according to the invention comprises encoding a first image; generating two reconstructions from the encoded first image, using two different reconstruction offsets; encoding a second image using temporal prediction based on a reference image selected from a set comprising the two reconstructions; wherein the obtaining of a different reconstruction offset comprises: partitioning the encoded first image to select the blocks of one partition, for example using criteria based on CTB, PU, TU of the HEVC standard or the Skip mode; for several reconstruction offsets, estimating a distortion measure based only on blocks collocated with those selected blocks, between the first reconstruction and an image reconstruction of the first image using each offset; and selecting the offset associated with minimum distortion.
