Imageencryption
这个工程实现了红绿蓝三个分量的提取,采用了新的方法,比传统的方法要清楚些,并且对红色分量做了DFT变换,用模版来对图像进行加密,为图像加密提供了一种新的思路。代码免费下载,功能优。(The project implements the extraction of three components red, green and blue, using a new method to make it clear than the more traditional methods, and components made of red DFT transform, the image used to encrypt the template for the image encryption provides a kinds of new ideas. Code free download, features excellent.)

GoldsequenceCDMAsimulation
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.)

此软件的基本功能主要分为2大模块:一个是数字图像处理模块,另一个是数字图像匹配模块。在数字图像处理模块中,用户可以对数字图像进行简单的处理,可以对图像进行放大,缩小,翻转,灰度处理。在数字图像匹配模块中,用户可以对两张图像进行匹配并显示匹配结果。(The basic function of this software is divided into two major modules: one is the digital image processing module, and the other is the digital image matching module. In digital image processing module, users can conduct a simple digital image processing, the right image to enlarge, reduce, flip, gray scale processing. In the digital image matching module, the user can match two images and displays matching results.)
