Image steganography technique is widely used to realize the secrecy transmission. Although its strategies on classical computers have been extensively researched, there are few studies on such strategies on quantum computers. Therefore, in this paper, a novel, secure and keyless steganography approach for images on quantum computers is proposed based on Moir´ e pattern. Algorithms based on the Moir´ e pattern are proposed for binary image embedding and extraction. Based on the novel enhanced quantum representation of digital images (NEQR), recursive and progressively layered quantum circuits for embedding and extraction operations are designed. In the end, experiments are done to verify the validity and robustness of proposed methods, which confirms that the approach in this paper is effective in quantum image steganography strategy.

最小选择恒虚警检测——SO-CFAR检测器：包括对于无目标、仅有噪声的信号进行SO-CFAR检测的仿真，以及对于含目标、且在瑞利杂波背景下的CA算法仿真。一些程序主要是为了绘图，画出SO-CFAR检测过程中的信号波形以及检测门限对比图；而另一些程序是为了计算SO-CFAR检测过程中的检测概率和虚警概率。(SO-CFAR detectors: simulations of detection to signals with no target but noise only, as well as signals with target and the background of Rayleigh clutter. Some programs are aimed at giving pictures of the signals and detectiong threshold in the process of detection using SO-CFAR algorithm, while other programs are aimed at calculating the detecting rate and false alarm rate of SO-CFAR algorithm.)
