METHOD, EQUIPMENT AND DEVICE FOR ENCODING AND DECODING Russian patent published in 2023 - IPC H04N19/105 H04N19/503 H04N19/182 

FIELD: encoding/decoding images.

SUBSTANCE: image encoding method is provided, comprising: when it is determined that weighted prediction should be enabled for a current block, the method includes: obtaining a weighted prediction angle of the current block for the current block; for each pixel position of the current block, determining a surrounding corresponding position indicated by the pixel position from surrounding positions outside the current block based on the weighted prediction angle of the current block; determining a target weight value of the pixel position based on a reference weight value associated with a surrounding corresponding position; determining an associated pixel position weight value based on the target pixel position weight value; determining a first pixel position prediction value based on a first prediction mode of the current block; determining a second pixel position prediction value based on a second prediction mode of the current block; and determining a weighted pixel position prediction value based on the first prediction value, the target weight value, the second prediction value and the associated weight value; and determining weighted prediction values of the current block based on the weighted prediction values of all pixel positions of the current block.

EFFECT: increased efficiency of encoding/decoding.
