利用LSB算法去实现了电子水印技术。代码完全实现了嵌入以及提取， 算法同时包含了4种攻击算法以及利用psnr测量提取的水印和攻击后提取的水印(This algorithm describes digital watermark technique by using LSB. This code implement embedding and extraction. At the meanwhile, this algorithm includes 4 different kinds of attacks and in the end, measure psnr between extracted watermark and attacked extracted watermark)

单色光（波）的双缝干涉实验的简单模拟：电磁场与微波技术、光学实验中，经常需要进行类似的干涉衍射实验，但受实验环境影响，结果误差大，用仿真模拟可以获得直观且纯净的结果。(Monochromatic light (wave), a simple simulation of the single-slit diffraction experiment: the electromagnetic field and microwave technology, optical experiments, often need similar interference diffraction experiments, but experimental environmental impact, results of large errors, the simulation can be intuitive and pure results.)

永磁同步电机基侧变流器simlink仿真，可直接运行(PMSM base side converter simlink simulation can be run directly)

This is the code for line count and character count in a scanned page..

K_Means聚类算法matlab实现，包含三个子函数，可用在图像处理中(K_Means clustering algorithm matlab realize, including three sub-functions that can be used in image processing)

产生随机共振现象的输入输出信噪比曲线，参数可以修改，不过不要乱改动哦，不然振动不起来了。(Stochastic resonance phenomenon generated input and output signal to noise ratio curve.)

说明：  对于给定的多个优化目标，用fgoalattain函数，解决简单的多目标规划问题(For a given number of optimization goals, with fgoalattain function, multi-objective programming to solve simple problems)

使用MATLAB程序通过18个循环,求最少费用的问题.(new Cumulative )

Preprocessing procedure in GNSS data processing

说明：  LMS (Least Mean Squares): most basic canonical ANC algo FxLMS (Filtered eXtended Least Mean Squares): adds an additional learned filter for the secondary path signal - signal from cancellation speakers to users ears - to account for phase problems and audio coloration added during practical noise cancellation applications NLMS (Normalized Least Mean Squares): adds simple adaptively updated learning rate on top of LMS to speed convergence. FxNLMS (Normalized Filtered eXtended Least Mean Squares): combines FxLMS and NLMS FuNLMS (Filtered-u Last Mean Squares): adds an additional active LMS filter to FxNLMS to cancel out noise bleeding from the cancellation speaker to the error mic. Fairly robust but convergence not gaurunteed!
