METHOD AND APPARATUS FOR ENCODING IMAGE BASED ON SUB-PICTURE Russian patent published in 2024 - IPC H04N19/82 H04N19/86 H04N19/117 H04N19/119 H04N19/132 

FIELD: images encoding and decoding means.

SUBSTANCE: residual samples are generated for the current block. Residual information is generated based on residual samples for the current block. Generating information relating to in-loop filtration for reconstructed samples of the current picture. Image information including residual information and information relating to in-loop filtration is encoded. Image information includes a sequence parameter set (SPS) and a picture header. When the SPS includes information relating to a sub-picture, information on the number of virtual boundaries and information on positions of virtual boundaries are not included in the header of the picture, but are included in the SPS.

EFFECT: higher coding efficiency.
