利用LSB算法嵌入隐藏图像，可在广义LSB中设置修改的位平面，返回误码率和峰值信噪比。含各种经典的攻击方式，可用于实验。并可控制攻击的强弱。利用Matlab编写。(LSB embedding algorithm using hidden images, can be generalized to set up modified LSB bit-plane and returned to the bit error rate and peak signal to noise ratio. Containing a variety of classic attack methods can be used for the experiment. Can control the strength of the attack. Prepared using Matlab.)

非线性方程组的最速下降法，数值计算基于matlab的源程序。(Steepest descent method based on the Matlab nonlinear equations, numerical calculation)

实现 harris角点提取，精度达到亚像素级，是基于matlab编程的。运行结果良好 。(For harris corner extraction, precision sub-pixel level, is based on matlab programming. Good operating results.)

说明：  matlab中的分数阶工具箱，文件中有两个，一个是的工具箱ninteger，一个是的FOTF(The fractional toolbox in matlab has two files, one is the foreign toolbox ninteger, and the other is the domestic FOTF.)

Program to use your camera as a scanner. Automatically detects the page on the picture. (Description Useful program if you don t have a scanner or need to scan quickly a lot of pages. It detects the page on the picture, make it rectangular, cut the borders and enhance the contrast. Function parameters are the input picture filename and output filename. Some parameters that can be changed are described in the function. Be careful with the flash of the camera, it creates a non-homogeneous luminosity difficult to clean. Required Products Image Processing Toolbox MATLAB release MATLAB 7.5 (R2007b) )

matlab编写的调整svm参数的程序，其中cross是主程序，另两个是自己编写的svm核函数，如果要用matlab自带的核函数就把-t的值改成2即可。Ytrain是标记矩阵，Xtrain是特征矩阵，都由用户自己导入。可利用k倍交叉验证来选择最优的c参数。k可自行更改。(svm matlab prepared to adjust the parameters of the program, which cross the main program, and the other two are themselves prepared svm kernel function, if you use the value of the kernel function matlab own put-t can be changed to 2. Ytrain is labeled matrix, Xtrain is characteristic matrix, imported by the users themselves. K-fold cross-validation can be used to select the optimal c parameter. k can make changes.)

说明：  求解语音信号的短时过零率、短时能量、短时自相关特征，分析实验结果，并能掌握借助时域分析方法所求得的参数分析语音信号的基音周期及共振峰。(The short-time zero-crossing rate, short-time energy and short-time autocorrelation characteristics of speech signal are solved, and the experimental results are analyzed. The pitch period and resonance peak of speech signal can be analyzed by the parameters obtained by time-domain analysis method.)
