METHOD AND EQUIPMENT FOR IMAGE ENCODING/DECODING TO PERFORM IN-LOOP FILTRATION BASED ON SUB-FRAME STRUCTURE AND METHOD FOR TRANSMITTING A BIT STREAM Russian patent published in 2023 - IPC H04N19/82 H04N19/86 

FIELD: image encoding.

SUBSTANCE: invention is related to image encoding/decoding method and equipment for performing in-loop filtering based on a subframe structure. The image decoding method implemented by the image decoding equipment comprises decoding the first flag indicating whether or not in-loop filtering can be performed across a subframe boundary from a bitstream, and performing in-loop filtering at a current block boundary based on the first flag. Based on the boundary of the current block coinciding with the boundary of the current subframe including the current block, in-loop filtering on the boundary of the current block is performed only when in-loop filtering is available for both the boundary of the current subframe and the boundary of an adjacent subframe adjacent to the current subframe.

EFFECT: increasing the efficiency of image encoding/decoding.
