说明：  将白噪声和瑞丽分布的噪声模拟为信号的背景噪声，分别通过小波去噪，EMD去噪，EMD结合小波去噪的方法来进行背景噪声去噪分析。(Ruili, the distribution of white noise and the noise modeled as background noise signals, respectively, through the Wavelet denoising, EMD denoising, EMD combined with wavelet denoising approach to denoising of background noise.)

this is matlab version of removal of noise

用MATLAB函数实现图像DCT域信息隐藏和提取，绘制控制阈值、JPEG压缩域与隐藏鲁棒性的关系图，对实验效果进行分析。(DCT domain information hidden field extraction)

采用matlab编程语语言，可在二维图片（对称）移动鼠标，自动检测出边缘轮廓，将二维图片转化为3维立体图片。(Using MATLAB programming language, the mouse can be moved in two dimensional picture (symmetrical), the edge contour is detected automatically, and the two-dimensional picture is transformed into 3 dimensional stereoscopic picture.)

说明：  利用MATLAB编写程序，用于识别人脸和检测人脸。(Use MATLAB to write programs for face recognition and face detection.)

本学期研一课程开设了数值方法，由于数值计算是MATLAB一项重要功能，所以结合MATLAB学习数值方法也许是条捷径！为了让大家更好的理解课程内容，更熟练第运用matlab解决数值计算问题，我根据上节课的内容，编写了《拉格朗日多项式逼近》与《牛顿多项式逼近》程序，以抛砖引玉，和大家共同提高！（其中部分程序参考数值方法（MATLAB版）一书） 附件里有m文件和详细的使用方法！ 希望让大家受益！(Lagrange polynomial approximation)

％ 用途：选列主元Gauss消去法解线性方程组ax=b ％ 格式：x=nagauss2(a,b,flag) a为系数矩阵，b为右端列向量，flag若为0，则显示中间过程 ％ 否则不显示，默认值为0，x为解向量 ( Usage: Selected Principal Gauss elimination method solution of linear equations ax = b format: x = nagauss2 (a, b, flag) a for the coefficient matrix, b for the right side column vector, flag if it is 0, it shows the middle Otherwise, the process does not appear, the default value is 0, x for the solution vectors)

小波包分析提取振动信号中的特征频率，有均匀线阵的CRB曲线，matlab开发工具箱中的支持向量机。( Wavelet packet analysis to extract vibration signal characteristic frequency, There ULA CRB curve, matlab development toolbox support vector machine.)

简单实用的基于偶排列的多相滤波吗matlab代码(Simple and practical, based on the even of a polyphase filter matlab code)

haar特征的提取，包括六种haar特征，再别人代码的基础上改进的，希望对大家有帮助。(haar feature extraction, including the six the haar characteristics, and the code of others on the basis of improvement, we hope to help.)
