Abstract :
Lin et al. proposed a non-expansion method to improve the image quality of the recovered image in visual cryptography by taking into account the distribution of black pixels. This paper proposes a new non-expansion method, which uses low computational cost to decrypt the shadow images and achieves reversibility.
