filter

说明：  使用傅里叶变换，希尔伯特变换求取一个信号的包络谱(Using Fourier transform and Hilbert transform to get the envelope spectrum of a signal)

这是我同学在IBM面试的一点资料，这里面包括笔试题目，面试题目，以及面试技巧。。 希望对想加入IBM蓝色之路的同仁有所帮助-This is my classmate in an interview that the information on IBM, which included a written examination subject, the interview subject, as well as interviewing techniques. . Want to want to join IBM Blue Tongren road help

Linear filter for image processing

说明：  常见有限差分格式构造，并有fortran代码实现，适合cfd学习(Common finite difference format construction, and FORTRAN code implementation, suitable for CFD learning)

基于sifi算法的手势识别项目，美国手语a--z(hand sign recognition)

用Python计算图像对不同地物分类精确度， 计算分类结果图与标准参考图的混淆矩阵， 对分类结果进行评价(Python was used to calculate the classification accuracy of images for different ground objects, calculate the confusion matrix between the classification result map and the standard reference map, and evaluate the classification results)

说明：  这是一个变电站的监控程序，数据库采用的是sql server7.0(This is a substation of the monitoring program, the database is used in sql server7.0)

该程序是DSP程序实现FIR运算，用来对输入信号的数据处理-DSP FIR Operational procedures used to the input signal, the data processing

局域网视频监控系统,本系统属于小型的局域网监控系统，可以对某一台计算机进行屏幕监控，本系统主要实现以下功能：  系统采用人机交互的方式，界面美观友好。  屏幕信息需要时时显示，网络延时不能大于1秒。  服务器端可以随时运行，只要客户端运行，就能够显示屏幕信息。  系统运行时占用内存不能大于10MB，以免影响系统性能。  客户端运行时需要隐藏显示窗口，起其感觉不到在运行。 -The system belong to a small local area network monitoring system can be carried out on a computer screen monitoring, implementation of this system is mainly the following functions: Human-Computer Interaction  system the way attractive and friendly interface.  screen display information required from time to time, the network delay should not exceed one second.  can run server-side, as long as the client is running, information on the display screen can.  system memory run-time should not exceed 10MB, so as not to affect system performance.  necessary run-time client to hide the window, starting at less than the feeling of running.
