视频监控，如果有东西经过监控区域就语音报警（有贼闯入）利用帧之间做差的方法(Video surveillance, if there are things after monitoring the regional voice alarm (the thief broke into) the use of the frame do the difference between method)

简单易用的matlab FFT程序，零频在中间，另外还经常用的matlab绘图代码列了出来(Simple and easy-to-use program matlab FFT, zero frequency in the middle, is also often used matlab drawing code out)

JPEG图像压缩编码及其MATLAB仿真实现，希望对大家有所帮助(JPEG image compression coding and MATLAB simulation, we hope to help)

Matlab图像滤波的源码，结合GUI，对于初学者，简单易用(Image Filtering Matlab source code, combined with GUI, for beginners, easy to use)

This is not my work but a function I use often. It is much faster than the conv2 function in matlab

BGA布线手册，很好，很强大！搞硬件的朋友可以看看！！！(BGA layout，very good ！)

说明：  matlab 图像灰度化代码，小波边缘检测(matlab image gray-oriented code, wavelet edge detection)

一篇学位论文，基于DSP的电力有源滤波器研究。用matlab仿真，并设计了模拟电路。(Write a dissertation, DSP-based Active Power Filter. Using matlab simulation, and design analog circuits.)

本文件是MATLAB编写潮流程序的课件，该课件简单易懂，特别适合电力系统潮流计算初学者自学。(This document is prepared by the trend of the program MATLAB courseware, the courseware easy to understand, especially for power flow calculation for beginners learning.)
