MSN机器人，可以自动恢复MSN联系人 大家可以 测试一下，看看如何...

基于ARM的俄罗斯方块设计，本次将设计实现一个用C语言编写的、在基于ARM核心的ADuC7020 ARM开发板上实现的单机版的俄罗斯方块小游戏。使用Keil3编程软件对C语言代码进行编写，支持按键操作，在实现过程中涉及了LCD液晶屏的图形显示、按键控制、LED控制、中断、蜂鸣器等嵌入式的编程技术。(Tetris ARM-based design, this will be designed to achieve a C language, the ADuC7020 ARM development board ARM core-based implementations of stand-alone version of the Tetris game. Use Keil3 programming software code written in the C language, support for key operations involved in the implementation process of the LCD screen graphical display, control buttons, LED control, interrupt, buzzer embedded programming techniques.)

此代码是基于DCT的数字水印MATLAB编程，包括水印的置乱和反置乱，嵌入以及提取水印四个部分(This code is based on digital watermark DCT MATLAB programming, including the watermark scrambling scrambling and anti-, four-part watermark embedding and extraction)

本程序是基于stm32单片机开发的心电图仪，包含ECG滤波算法，通过串口发送数据给PC上位机。(This procedure is based on STM32 microcontroller development of the ECG, containing the ECG filter algorithm, through the serial port to send data to the PC host computer.)

这是一段求信息量的C++程序,对输入的一组数据进行求和,及最终算出其信息量和信道容量(This is for the amount of information for some of the C++ Procedures, a group of input data summation, and finally calculate the amount of information and channel capacity)

应用Opencv中的函数来实现大津算法，实现阈值的自适应获取，从而进行图像分割。(Otsu，image segmentation)

音频信号降采样程序 支持48k->8k 24k->8k 8k->1k 的降采样.实现方法,先做低通滤波,再做采样点抽取.低通滤波起使用67点FIR,系数由matlab使用窗函数法生成 (Audio signal down-sampling procedures to support the 48k-)

关于FTP的代码,支持网络间的文件传输,用户权限的设定.(on FTP code, the support network file transfer, set user privileges.)

zigbee实现LCD的检测，测试LCD能否正常工作,LCD的型号是12684(zigbee achieve the LCD inspection, testing LCD can work, LCD model is 12,684)

这个程序是POS机ANSIX9.9算法验证工具(This program is under the POS machine ANSIX9.9MacTool)

关于rtsp流媒体服务器基于live555的搭建程序。传者已修改验证过可用，奉献出来供大家参考使用，可用作学习和研发。
