Abstract
A method for determining a motion vector of a specific macro-block of an image frame includes: determining a plurality of motion vectors of a plurality of macro-blocks of the image frame, wherein the macro-blocks comprise at least the specific macro-block and its neighboring macro-blocks; determining weighting factors of the macro-blocks; for a first motion vector of the plurality of motion vectors, determining a cost of the first motion vector according to at least a portion of the weighting factors and the motion vectors; for a second motion vector of the plurality of motion vectors, determining a cost of the second motion vector according to at least a portion of the weighting factors and the motion vectors; and refining determination of the motion vector of the specific macro-block according to the cost of the first motion vector and the cost of the second motion vector.
