Abstract:
1. An image search method, comprising: determining, in a processor, a quadrant of a predicted motion vector; calculating, in the processor, a tilt value of a first reference frame and a tilt value of a second reference frame using the predicted motion vector; deciding, in the processor, a search area for uneven hexagon search in response to the quadrant of the predicted motion vector and the calculated tilt values; performing, in the processor, the uneven hexagon search with respect to the decided search area; and comparing, in the processor, a result of the performed uneven hexagon search with a threshold value to determine termination of the uneven hexagon search; wherein the quadrant of the predicted motion vector is defined by an angular displacement of the predicted motion vector, and wherein the second reference frame is earlier-in-time relative to the first reference frame.
