FIELD: physics.
SUBSTANCE: invention relates to image encoding and decoding. Such a result is achieved by determining whether bidirectional optical flow (BDOF) or prediction granularity using optical flow (PROF) is applied to the current block, based on the BDOF or PROF applied to the current block, fetching a predictive selection of the current block from the reference frame of the current block based on motion information of the current block and extracting the detailed prediction sample for the current block by applying BDOF or PROF to the current block based on the sampled forecast sample.
EFFECT: efficient encoding and decoding.
