System and method for steganographic image display

摘要

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.

1. A computer-implemented method for generating images, the method comprising:
receiving a first target image comprising a first human-perceptible image; receiving a second target image, dissimilar from the first target image, comprising a second human-perceptible image; subtracting the second target image from the first target image, at each image location, to generate a first display image; generating a second display image that is perceivable as the second target image; splitting the second display image into a third display image and a fourth display image, wherein neither the third display image nor the fourth display image is recognizable as the second target image, and multiplexing the first display image with the third display image and the fourth display image to generate a fifth display image that is perceivable as the first target image when viewed in an ambient setting; wherein the fifth display image, when viewed via a visual aid, is perceivable as the second target image.
