METHOD AND DEVICE FOR IMAGE ENCODING USING MOTION VECTOR DIFFERENCES Russian patent published in 2023 - IPC H04N19/105 

FIELD: image encoding.

SUBSTANCE: invention is related to image encoding using motion vector differences. The result is achieved in that a prediction procedure can be performed for image/video encoding and can include symmetric motion vector differences (SMVD) and merged motion vector differences (MMVD) in accordance with inter-prediction. Inter-prediction may be performed based on the reference pictures of the current picture, and the types (e.g., long-term reference picture, short-term reference picture, etc.) of the reference pictures may be taken into account for inter-prediction.

EFFECT: increasing the encoding efficiency.
