基于simulink的三相PLL锁相环仿真,可以直接使用(Three phase PLL phase lock simuliation，it can be used directly)

最小二乘回归分析算法，进行逐步线性回归，实现了图像的加水印，去噪，加噪声等功能。( Least-squares regression analysis algorithm, Stepwise linear regression, Realize image watermarking, de-noising, plus noise and other functions.)

提出了一种离散小波变换域实现图像水印的方法。这种算法充分利用小波变换的特点,把原始图像及水印图像塔式分解,在多分辨率分解后的相同的频段来嵌入水印信息。该方法也利用了人眼视觉特性,算法简单而有效。实验证明,该算法较好地解决了水印不可见性与鲁棒性之间的矛盾,对常见的水印攻击都有较强的鲁棒性。(presents a discrete wavelet transform domain image watermarking method. This algorithm using wavelet transform characteristics, the original image and the watermark image tower decomposition, Multiresolution decomposition in the same frequency band to the embedded watermark. The method has also been used HVS, the algorithm is simple and effective. Experiments show that the algorithm can solve the watermark is visible with the robust nature of, common to have more attacks watermark robustness.)
