<P>PROBLEM TO BE SOLVED: To provide a technique that determines the vertical direction by focusing on information in an image other than characters and brightness at four corners. <P>SOLUTION: People are mostly on the ground, floor or the like, where they normally take different positions on the horizontal direction. In an image having a plurality of persons, the plurality of persons tend to be arranged side by side so that face images (skin regions) are disposed horizontally rather than vertically. Hence, the skin regions in the image are extracted, the dispersion of the skin regions is computed in two orthogonal directions, and the vertical direction is determined from the computations. <P>COPYRIGHT: (C)2007,JPO&INPIT |
