Abstract:
1. A system comprising: an input for receiving a bit stream; a storage having a graphical pattern representing a bit and another graphical pattern representing another bit, wherein the graphical patterns are comprised of dark and light pixels; a processor for encoding the bit stream into an encoded bit stream using the graphical patterns, said encoded bit stream corresponding to an overall graphical pattern, wherein the overall graphical pattern is configured to eliminate a type of shape by juxtaposing together the graphical patterns representing the bits; and, an output for outputting the encoded bit stream as the overall graphical pattern, wherein the overall graphical pattern comprises orientation information to recover a location of a captured image with respect to the overall graphical pattern, the captured image being a copy of a portion of the overall graphical pattern, wherein the orientation information is found by rotating the captured image until determining a lack of the type of shape within the captured image, the lack of the type of shape indicating an orientation from which the encoded bit stream can be decoded.
