METHOD AND EQUIPMENT FOR ENCODING/DECODING IMAGE FOR PERFORMING DEBLOCKING FILTERING BY DETERMINING BOUNDARY INTENSITY AND METHOD FOR TRANSMITTING BITSTREAM Russian patent published in 2024 - IPC H04N19/86 

FIELD: physics.

SUBSTANCE: invention relates to encoding/decoding images. Result is achieved by the fact that the image decoding method according to the present invention can comprise obtaining a reconstructed frame, determining a target filtering boundary for deblocking in the reconstructed frame, determining boundary intensity for the target boundary and applying de-blocking filtering to the target boundary based on the boundary intensity. Based on the target boundary, which is the boundary of the transformation unit, and the colour component, which is the component of the colour signals of the reconstructed frame, the boundary intensity can be determined based on whether combined residual CbCr coding is performed or not for at least one of two blocks adjacent to the target boundary, and combined residual CbCr coding may correspond to coding of residual samples for Cb component of chroma signals and Cr component of chroma signals as one conversion unit.

EFFECT: high efficiency of encoding/decoding images.
