实现窗口管理功能，文本编辑器，讲word功能集合在记事本软件上。(Achieve window management function, the text editor, talk about the function of word collection in Notepad software.)

基于Qt的UDP组播例程，包括服务器和客户端，系统平台Windows(Qt-based UDP multicast routines, including server and client system platform Windows)

通过一个非常简单的程序来开始学习QT，了解QT的基本程序框架结构(Through a very simple program to start learning QT, QT understand the basic program framework)

用Qt绘制实时曲线，主要用到scroll函数，代码非常简单，适合新手学习，在windows下运行(Use Qt to draw real-time curve, mainly used in the scroll function, the code is very simple, suitable for novice learning to run under windows)

qt 进程间通信，windows系统下运行，可以有两种方式 QLocalSocket 或 QSharedMemory(qt inter-process communication, windows system running, there are two ways QLocalSocket or QSharedMemory)

读取csv文件的数据，按要求拉算出平均数(Read csv file data, calculate the average number required to pull)

提供了360界面设计的源码，有需要的朋友下载看看，界面和360杀毒软件是一样的，只提供了界面，可以自行修改界面的内容，十分使用

qt中listview做了一个列表，可拖动，高亮，放大。返回等(qt listview do a list, you can drag, highlight, zoom. Returns, etc.)

使用QT开发的示波器源码，实现示波器的基本功能，可供初学者参考学习。(Oscilloscope source By QT)

sift算法在cv领域的重要性不言而喻，该作者的文章引用率在cv界是number1.本篇博客只是本人把sift算法知识点整理了下，以免忘记。本文比较早的一篇博文opencv源码解析之(3)：特征点检查前言1 中有使用opencv自带的sift做了个简单的实验，而这次主要是利用Rob Hess的sift源码来做实验，其实现在的opencv版本中带的sift算法也是Rob Hess的，只是稍微包装了下。 下面来做下试验,试验sift代码采用Rob Hess的代码，opencv目前版本中的sift源码也是采用Rob Hess的。代码可以在他的主页上下载：http://blogs.oregonstate.edu/hess/code/sift/ 这里我下载的是windows版本的，并采用Qt做了个简单的界面。(sift algorithm is self-evident the importance of the cv field, the author of the article referenced in the cv sector is number1 this blog I just sift algorithm knowledge compiled under, so as not to forget. This article compares the earlier blog post opencv source code analysis (3): check the preface of the feature points 1 the opencv bring their own sift to do a simple experiment, but this time Rob Hess' s sift source to experiment. In fact, with the opencv version sift algorithm is Rob Hess, only slightly packing the next. Below to do the next test, test sift code using the code of Rob Hess, sift source opencv version of Rob Hess. The code can be downloaded on his home page: http://blogs.oregonstate.edu/hess/code/sift/ here I downloaded the windows version, and using Qt to do a simple interface.)
