1. At least one physical method comprising: determining a point within a macroblock to be predicted; computing an epipolar line based on the point within the macroblock to be predicted; determining a temporary starting point in the macroblock to be predicted, wherein computing the epipolar line comprises determining fundamental matrix F based on a relative position of first and second cameras to be predicted the macroblock to be predicted; determining a search starting point based on the temporary starting point and the epipolar line; and wherein the method is performed by a computer.
