Abstract

The ability of the human visual system to integrate a rapidly oscillating image in time is investigated in this paper. A secret image is encoded into a stochastic geometric moiré grating. The secret is leaked in the form of a pattern of time-averaged moiré fringes when the cover image is oscillated according to a predetermined law of motion. Special encoding algorithms are designed for an effective real-time implementation of the scheme on a digital computer screen. A series of experiments is performed to determine the minimum frequency of oscillations required for the interpretation of the embedded secret image.
