  • System and method for steganographic image display
    Patent number: 8890892
    Abstract: A computer-implemented method for generating images. The method includes receiving first and second target images. The method further includes computing a delta image based on a difference between the first target image and the second target image and a technique for multiplexing a first display image with the delta image, where the first display image multiplexed with the delta image, when viewed by a person in an ambient setting, is perceived as the second target image. Advantageously, a hidden image is obscured from an ambient observer, while still providing the ambient observer with a target image that is intended to be perceived.
