Adaptive coding method and device

摘要

The method containing a pre-analysis phase (6) with pel-recursive type motion estimation and an actual coding phase with block matching motion estimation (11) for picture blocks constituted by one or more sub-blocks, characterised in that the coding phase also comprises
- a motion vector selection stage for the picture sub-blocks based on the motion vectors calculated by matching for the block containing the sub-block and based on the motion vectors calculated by the pel-recursive type estimation for the pixels or the pixel groups belonging to the sub-block,
- and a calculation stage of the best partition of a picture block into sub-blocks based on the correlation calculations taking into account the motion vectors selected from the sub-blocks constituting a block.
