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 H04N19/513 H04N19/20 G06T9/00 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to predictive motion vector predictive encoding/decoding of moving pictures. The moving picture encoding apparatus includes a primary candidate reference motion vector determination unit which sets N primary candidate reference motion vectors, a degree of reliability calculation unit which calculates the reliability of each primary candidate reference motion vector which quantitatively represents effectiveness in motion vector prediction of the block to be decoded, using encoded or decoded picture information, a reference motion vector determination unit selects M (M<N) secondary candidate reference motion vectors in accordance with the degree of reliability of N primary candidate reference motion vectors, a motion vector encoding unit calculates a predictive motion vector of the block to be encoded using M secondary candidate reference motion vectors with high reliability.

EFFECT: improved efficiency of predicting and encoding moving pictures.
