Zusammenfassung:A mobile platform captures a scene that includes a real world object, wherein the real world object has a non-uniform pattern in a predetermined region. The mobile platform determines an area in an image of the real world object in the scene corresponding to the predetermined region. The mobile platform compares intensity differences between pairs of pixels in the area, with known intensity differences between pairs of pixels in the non-uniform pattern, to identify any portion of the area that differs from a corresponding portion of the predetermined region. The mobile platform then stores in its memory, a value indicative of a location of the any portion relative to the area. The stored value may be used in any application running in the mobile platform.
