直序扩频通信系统仿真实例,信源为数字信号信道信噪比为10dB的直扩通信系统仿真实验simulik文件(Direct sequence spread spectrum communication system simulation example, the source for digital signal channel SNR for 10 db of spread spectrum communication system simulation simulik file)

给出了MATLAB语言实现IIR滤波器的实现，源文件中还有原理方法(MATLAB language are given the realization of IIR filters, there is the principle source document method)

这写都是我在做-x LMS噪声除噪中的一些源代码，最后的代码也有，请大家自己看(It was all my doing-x LMS noise than noise in some of the source code, the final code also, please look at their own)

matlabcontourlet变换结合了不可分离的方向滤波组,具备小波所不能表达的多方向特性,能有效捕获自然图像的边缘轮廓信息。本文分析了图像ontourlet系数的统计特征,并利用广义高斯函数对各子带系数层进行建模。将此模型应用于基于VisTex的自建纹理图像库,采用矩匹配估计法,提取模型参数集,运用K2L (matlab)

中值滤波快速算法，对搜索框的排序进行归并排序，并利用前一个已排好的结果(Fast median filtering algorithm)

This is the explanation about the data encryption, and this can be mostly used in the stegnography and cryptography, This encrypts the data such as image or any data file and can be used in hiding.

Fast video loading code do background subtraction subtracting all frames from first frame and show the result video so fast

说明：  饼状图绘制的MATLAB程序。需要的来下载。(Pie mapping procedures of the MATLAB. Need to download.)

this code is for fingerprint thinning
