IMAGE ENCODING METHOD, IMAGE DECODING METHOD, IMAGE ENCODING DEVICE, IMAGE DECODING DEVICE AND APPARATUS FOR ENCODING AND DECODING IMAGES Russian patent published in 2017 - IPC G06T9/00 H04N19/119 H04N19/124 H04N19/96 

FIELD: data processing.

SUBSTANCE: invention relates to video encoding/decoding. Disclosed is a method of decoding images. Method includes a step of decoding an encoded signal, to generate quantisation coefficients and control information fragments, wherein quantisation coefficients correspond to appropriate one of transformation units, and control information fragments indicate structure of transformation units. Further, method comprises inverse quantisation and inverse transformation for each of quantisation coefficients, ultimately forming prediction error signals of corresponding transformation units. Method also includes summation of one of prediction error signals with a predication signal for each of coding units, including transformation unit, ultimately forming decoded signals for each of coding units.

EFFECT: high efficiency of decoding images.
