MOVEMENT EVALUATION TECHNIQUES Russian patent published in 2014 - IPC H04N19/557 G06T7/20 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to video and image processing techniques, particularly a movement evaluation device and method. Disclosed is a method of determining a motion vector between a reference image and a current image, comprising steps of: determining, using a computation module, a plurality of lower bound values of the measured error for a block in the stored current image, wherein each of said lower bound values of the measured error matches the stored search position in the stored reference image; determining a division threshold using lower bound values of the measured error for the block in the stored current image; selecting a plurality of candidate positions from the plurality of search positions based on the determined division threshold; identifying one of the candidate positions as a matching position for the block in the current image; and determining, using the computation module, a motion vector based on the block in the current image and in the matching position.

EFFECT: reduced computational load on movement evaluation.
