Application Number: JP,2025-020501
Category (FI): H04N19/176,H04N19/70,H04N19/513,H04N19/51
Stage: PROBLEM TO BE SOLVED: To provide a method, encoding device, decoding device, system, and storage medium, for supporting a bi-directional optical flow (BDOF).SOLUTION: A method of decoding implemented by a video decoder includes: determining whether a resolution of a current picture being decoded is the same as resolutions of reference pictures identified by a reference picture list associated with the current picture; enabling, by the video decoder, a BDOF for a current block of the current picture when the resolution of the current picture is determined to be the same as the resolution of each of the reference pictures; disabling, by the video decoder, the BDOF for the current block of the current picture when the resolution of the current picture is determined to be different from a resolution of either of the reference pictures; and refining, by the video decoder, motion vectors corresponding to the current block using the BDOF when the BDOF is enabled for the current block.SELECTED DRAWING: Figure 10 (Grant)
