FEATURES OF INTRA BLOCK COPY PREDICTION MODE FOR VIDEO AND IMAGE CODING AND DECODING Russian patent published in 2018 - IPC H04N19/50 H04N19/52 H04N19/82 H04N19/176 

FIELD: electrical communication engineering.

SUBSTANCE: invention relates to encoding/decoding video. Method of performing in-loop deblock filtering across a boundary between blocks, which is implemented in a computing device, comprises steps of: reconstructing first and second blocks of a picture, wherein the picture includes at least some blocks with prediction mode of intra block copy prediction, and performing in-loop deblock filtering across a boundary between the first and second blocks, wherein the first and second blocks are encoded using intra block copy prediction, wherein in-loop deblock filtering includes setting loop deblock filtering based, at least in part, on the values of the block vectors (BV), determined for the first and second blocks, respectively.

EFFECT: technical result is providing efficient data compression in the context of the distortion rate versus the transmission rate, by using the filtered sample values for intra block copy prediction.
