MOVING GRAPHIC IMAGES CODING METHOD, MOVING GRAPHIC IMAGES CODING DEVICE, MOVING GRAPHIC IMAGES DECODING METHOD AND MOVING GRAPHIC IMAGES DECODING DEVICE Russian patent published in 2017 - IPC H04N19/463 H04N19/91 H04N19/82 

FIELD: information technology.

SUBSTANCE: method for moving graphic images coding for input image encoding. Method comprises the step of performing conversion of the first image pixel classification parameter values using a transmitter to a binary form to the first binary signal, wherein the first parameter identifies the type of sample displacement process which must be applied to the recovered image corresponding to the input image. Further, according to the method, encoding of the first part of the first binary signal is carried out by context-adaptive arithmetic coding, and encoding of the second part of the first binary signal is carried out by a bypass arithmetic coding using a fixed probability.

EFFECT: increased image encoding and decoding efficiency.
