本软件具有简单的界面，能够通过简单的操作对图像进行水印加密、图像篡改检测、图像篡改定位、图像篡改修复。(The software has a simple interface that can be encrypted watermark image by a simple operation, image tamper detection, image tamper localization, image tampering repair.)

在参数辨识中，利用镜像映射法求解超定方程组(In the parameter identification, the use of image mapping method to solve the overdetermined system of equations)

Makes a simple avi movie from a sequence of frames The user can control the display time of each frame. The movie is created in the same folder where this function is run. Usage: Inputs: name: root name of the framse filetype: .bmp , .jpg , .jpeg , .tif ,,,, number_of_frames: number of the frames display_time_of_frame: it is the display time of each frame Output: it creates a file named as Movie.avi in the same folder of this function

This paper investigates the behavior of one particular near-far resistant detector, the parallel fractional adaptive detector

fdatool工具箱的数字滤波器设计详解总结，包括滤波器参数设置及意义(fdatool digital filter design toolbox Detailed summary, including the filter parameters and the significance of )

说明：  通过matlab代码，验证了带通采样定理的正确性(The bandpass sampling theorem is realized.)

写一个MATLAB程序，实现4个时间同步的CDMA用户的仿真，其中每个用户都使用长度为L=31的不同的Gold序列。每个用户都采用它们代表的Gold序列的二进制（+-1）调制。每个用户的接收端将这个复合的CDMA接收信号相关，而这个复合的信号都在它们各自的序列上受到AWGN的污损（基于按码片相加）。在N=10000信息比特下，仿真估值并画出作为SNR的函数的CDMA通信系统的差错概率。(Write a MATLAB program, the realization of the four time synchronization of the simulation of CDMA users, including the length of each user for use of the L = 31 different Gold sequences. They are used for each user on behalf of the Gold sequence of binary (+-1) modulation. Each user' s receiver will receive the composite CDMA signal, and this composite signal in the sequence of their respective defaced by the AWGN (additive based on the chip by). Information in the N = 10000 bits, the simulation value and draw as a function of SNR of the CDMA communication system the probability of error.)
