<p>Determining (20) a best match between a first pixel array in a first picture and a plurality of second pixel arrays in a search region of a reference picture is provided. The method includes the steps of providing (22) a first full orthogonal-sum signature of the first pixel array comprised of a set of horizontal sums and a first set of vertical sums; providing (22) a plurality of partial orthogonal-sum signatures for respective ones of the plurality of second pixel arrays; concurrently computing (25) a plurality of second full orthogonal-sum signatures for the respective ones of the plurality of second pixel arrays using the plurality of partial orthogonal-sum signatures; and, comparing (27, 29, 31, 33) the first full orthogonal-sum signature with each of the second full orthogonal-sum signatures in order to determine the best match between the first and second pixel arrays.</p> |
