Barlette 方法估算入射信号源的到达角的方法，使用Matlab工具。(a simple and good Barlette method for doa estimation.)

包含三维obj格式的模型，并用matlab读取并显示，程序可用。(Contains a three-dimensional model of obj format, using matlab read and display, the program is available.)

application与config对象。李兴华老师上课的笔记，具体在优酷上可以搜到。配套使用(application and the config object. Li Xinghua teacher in the class notes, specifically in the superior can be found to cool. Supporting the use of)

This is a GUI program developed in matlab. It can be used for recording the speech signals & storing them to the .wav files. This GUI further provides the interfaces to plot the recorded speech signal. Also, the recorded samples are used for training purpose of a speech recognition system. All the required files are included in the same folder.

关于AR模型的burg、yulear功率谱估计算法，与系统自带的pburg相比，精确度更高(ar burg yulear)

该代码实现了图像的滤波处理，这段代码给出了三种滤波矩阵，包括图像平滑(低通滤波器)、图像边缘提取(高通滤波器)等。用户下载后可以根据自己需要修改滤波矩阵和参数值，以便实现特殊的功能。为了形象的说明滤波效果，代码执行后可以看到滤波前后滤波后的对比图像。 (The code of the image filter processing, the code shows the three filter matrix, including the smoothing (low pass filter), image edge detection (high-pass filter) and so on. Users can download their own need to modify the filter matrix and the parameter values in order to achieve a specific function. Filtering effect to the image description, code execution before and after filtering can be seen after comparison of the filtered images.)

说明：  多目标跟踪软件流程如下： 初始化函数 初始化轨迹对象 读取一帧数据 前景检测 根据位置进行卡尔曼预测 匈牙利匹配算法进行匹配 分配好的轨迹更新 未分配的轨迹更新 删除丢掉的轨迹 创建新轨迹 结果展示(The flow of multi-target tracking software is as follows: Initialization function Initialize track object Read a frame of data Foreground detection Kalman prediction based on location Hungarian matching algorithm for matching Assigned track update Unassigned track update Delete lost tracks Create a new track Result display)

用元胞自动机模拟交通流,这是一个在二维格子上的元胞自动机，可以当做游戏来看看(use cellular_automata to simulate the traffic flow)

this is a matlab code for zooming image

两个图像的峰值信噪比（psnr）计算公式 归一化系数计算 dwt嵌入数字水印(PSNR of two images (psnr) formula normalized coefficients dwt Watermarking)
