A-Novel-Strategy
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.

心音的分析
信号的频域处理可分为经典方法和现代方法。经典方法以傅利叶变换为核心，只处理线性时不变问题。对非线性时变问题的处理是正在发展中的现代方法内容。经典的谱估计方法对采样得到序列进行处理隐含了一个加窗的操作，窗外的数据默认为零。所以可靠经典的谱估计方法在采样点数比较少的情况下，对频率的估计变得不可靠。现代谱估计方法以模型为基础，利用采样的数据建立模型，使谱估计的结果更能体现随机信号全局性的性质。(Heart sound analysis technology)
