|Abstract: ||In this paper, we propose a novel method called DHSED to hide binary visual patterns in two error diffused halftone images. While one halftone image is only a regular error diffused image, stochastic error diffusion is applied to the other image to generate special stochastic characteristics with respect to the first image such that the visual pattern would appear when the two halftone images are overlaid. Simulation results show that the two halftone images have good visual quality, and the hidden pattern appears with 'normal' and 'lower-than-normal' intensity when the two halftone images are overlaid.|
