METHOD AND DEVICE FOR PREDICTING INTER-FRAME MOTION VECTORS AND DISPARITY VECTORS IN 3D CODING OF VIDEO SIGNALS Russian patent published in 2017 - IPC H04N19/52 H04N19/139 H04N19/176 G06T7/20 

FIELD: physics.

SUBSTANCE: method of extracting candidate motion vector (MV) or disparity vector (DV) for the block in the image includes: obtaining the data related to the current motion vector or disparity vector of the current block of the original image; extracting a candidate motion vector (MV) or a disparity vector (DV) from the block image at the next frame; using predictive coding to the motion vector or the disparity vector of the current block of the original image on the basis of the motion vector prediction (MVP) or the disparity vector prediction (DVP), including the candidate motion vector (MV) or a disparity vector (DV); and verifying the information about the motion of the unit image at the next frame, and if the traffic information of the unit image at the next frame is not valid for the current block using the disparity vector (DV) of the unit image at the next frame as the motion vector of the image block in the nearest frame.

EFFECT: simplifying the process of extracting a candidate motion vector or disparity vector for the image block.
