IMAGE ENCODING METHOD AND DEVICE FOR LOOP FILTERING CONTROL Russian patent published in 2023 - IPC H04N19/82 

FIELD: image encoding.

SUBSTANCE: device and method for encoding an image to control contour filtering. Determining the presence of signaling information related to virtual boundaries is present in the sequence parameter set (SPS) or picture header information is determined based on the virtual boundaries enable flag. Moreover, the image information includes a sequence parameter set (SPS) and picture header information referring to the SPS, wherein the SPS includes virtual boundaries enable flag, and further in-loop filtering process is performed on the virtual boundaries based on the determination.

EFFECT: increasing the encoding efficiency.
