METHOD AND EQUIPMENT FOR ENCODING/DECODING IMAGES FOR PERFORMING IN-LOOP FILTERING BASED ON SUBFRAME STRUCTURE AND METHOD FOR TRANSMITTING BIT STREAM Russian patent published in 2025 - IPC H04N19/86 H04N19/82 

FIELD: data processing.

SUBSTANCE: invention relates to image encoding/decoding equipment for performing in-loop filtering based on a subframe structure. Encoding equipment for encoding images comprises a memory device; and at least one processor connected to the storage device. Processor is configured to determine whether or not intra-loop filtration can be performed through a subframe boundary, and based on the result of determining whether to perform intra-loop filtration at the boundary of the current block. Based on the boundary of the current block, which coincides with the boundary of the current subframe, which includes the current block, in-loop filtering at 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 a neighbouring subframe adjacent to the current subframe.

EFFECT: high efficiency of encoding/decoding images.
