DEVICE FOR ENCODING MOVING FRAMES, A METHOD FOR ENCODING MOVING FRAMES, A DEVICE FOR DECODING MOVING FRAMES, A METHOD FOR DECODING MOVING FRAMES Russian patent published in 2022 - IPC H04N19/52 H04N19/105 

FIELD: imaging technology.

SUBSTANCE: invention relates to means for encoding and decoding moving frames. An affine inherited possible combination option is extracted to inherit the affine model of blocks adjacent to the target coding block in the spatial domain. An affine constructed possible combination option is extracted from a set of information elements of the movement of blocks adjacent to the target encoding block in the spatial or temporal domain. An affine fixed possible combination option is extracted, in which the information of the movement of the affine control point is fixed. In this case, the motion vector of each affine control point is set fixed equal to (0, 0) in the affine fixed possible combination option.

EFFECT: increase in the encoding efficiency by performing block splitting.
