WebMay 15, 2006 · Abstract. A technique of optical image hiding in the Fresnel domain is proposed. In our method, a secret image can be hidden in the watermarked image through the phase only masks that are efficiently generated by the phase retrieval algorithm. The corresponding key distribution scheme is also investigated. Since the watermarked image … WebApr 1, 2014 · We present a completely optical scheme for image hiding that is based on phase-shifting interferometry in a modified Mach–Zehnder interferometer. The original object is placed in one path of the modified Mach–Zehnder interferometer, and the host image is located in the other path.
