MOTION VECTOR PREDICTIVE ENCODING METHOD, MOTION VECTOR PREDICTIVE DECODING METHOD, MOVING PICTURE ENCODING APPARATUS, MOVING PICTURE DECODING APPARATUS, AND PROGRAMMES THEREOF Russian patent published in 2014 - IPC H04N19/517 H04N19/139 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. The motion vector predictive encoding method in a moving picture coding scheme comprising motion detection for a unit in an image using an encoded reference image for calculating a motion vector; selecting N (N is an integer equal to or greater than 2) motion vectors which include motion vectors used to encode encoded units, or motion vectors having a predefined value as primary candidate reference motion vectors; calculating the degree of reliability of each of the N primary candidate reference motion vectors; selecting the primary candidate reference motion vectors with a degree of reliability greater than a predefined threshold value from the N primary candidate reference motion vectors as secondary candidate reference motion vectors; calculating a predictive motion vector of a unit using secondary candidate reference motion vectors and encoding the remainder between the motion vector obtained by detecting movement of a unit, and the predictive motion vector as encoded motion vector information.

EFFECT: improved efficiency of motion vector prediction.
