Abstract (en)

[origin: WO2021134393A1] A deblocking method for video coding is disclosed, which comprises: determining one or more sections on a boundary of a constructed block, wherein the constructed block is predicted by a non-rectangular inter prediction mode; determining each sub-area based on each of the one or more sections, wherein the sub-area is a rectangular sample array and comprises samples of the constructed block and a neighboring block of the constructed block; determining a filtering strength based on weighted prediction parameters of the neighboring block and/or the constructed block; and performing deblocking filtering on the sub-area.
