Abstract (en)
[origin: WO2020251420A2] A method of performing a deblocking filter for blocks predicted by using intra block copy prediction mode, the method performed by coding device, the method comprising the following steps: determining a position of a reference block, constructing a prediction for the current block from the reference block, performing a deblocking process for each color component, comprising: calculating the boundary strength for each sub-block of the current block in vertical direction, respectively, performing deblocking filtering in vertical direction, calculating the boundary strength for each sub-block of the current block in horizontal direction, respectively, and performing deblocking filtering in horizontal direction; wherein the size of each sub-block is at least 4x4.
