摘要：
In image encryption based on moire pattern, a secret image is hidden to an encrypted image by a reference fringe pattern. When the reference fringe pattern and the encrypted image are superimposed or by simple computation, the secret can be reconstructed. Generating reference fringe pattern and encrypted image depends on selection of different parameters. Although some experimental results demonstrate validness of their algorithms based on moire pattern, related parameters are not given. In this paper, we first discuss two superimposition models for grey-scale image and analyze reconstructed images with different parameters, and then obtain relationship among reconstruction quality and parameters of generating equations. Experimental results show the validness of the obtained relationship among reconstruction quality and different parameters.
