IMAGE ENCODING METHOD, IMAGE DECODING METHOD, IMAGE ENCODING DEVICE, IMAGE DECODING DEVICE AND IMAGE ENCODING AND DECODING DEVICE Russian patent published in 2020 - IPC G06T9/00 H04N19/119 H04N19/124

Abstract RU 2711755 C2

FIELD: physics.

SUBSTANCE: invention relates to video encoding/decoding. Method of encoding images comprises steps of: subtracting the prediction signal from the input image signal for each coding unit, thereby generating corresponding prediction error signals; performing orthogonal transformation and quantisation for corresponding one of prediction error signals for each conversion unit, ultimately forming quantisation coefficients; and encoding control information fragments indicating the transformation units structure and quantisation coefficients into the tree structure.

EFFECT: technical result is higher efficiency of images encoding.
