Abstract
Systems and methods of graphically demodulating a graphical bar code (i.e., an image that contains inconspicuous graphical modulations that encode information embedded in an original base image) are described. The graphical bar code may be graphically demodulated automatically without foreknowledge of the original unmodulated base image, but rather based upon a base image that is derived based upon intrinsic features of the graphical bar code.
