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. The information necessary to control the in-loop filtering performed on the virtual boundaries can be effectively signaled by the encoder. Thus, information related to whether in-loop filtering at virtual boundaries is available may be signaled. Wherein the picture information includes a sequence parameter set (SPS) and picture header information referring to the SPS, and the information related to virtual boundaries includes a virtual boundary enable flag, thereby determining whether signaling information related to virtual boundaries is present in SPS or picture header information, is determined based on the virtual boundaries enable flag, and further in-loop filtering process is performed on the virtual boundaries based on this virtual boundaries enable flag.

EFFECT: increasing the encoding efficiency.
