说明：  摄像头OV7670模块调试资料，硬件参考电路、51、STM32源码。(Camera OV7670 module debugging data, hardware reference circuit, 51, STM32 source code.)

利用c++程序来实现voronoi图的生成，十分简单、有效(Using c++ program to achieve the generation of Voronoi diagram, very simple and effective)

使用51单片机实现最简单的PPM编码，让初学PPM编码的更好的了解并采用此方法作进一步改进

以NACA0012 翼型为研究对象，采用拉格朗日法分析了重力对水滴撞击特性的影响，获得了过冷大水滴(SLD)撞击特性。(The influence of gravity on the droplet impingement property were analyzed with the Lagrangian method, and the supercooled large droplet (SLD) impingement property has been gotten based on the research of NACA0012 airfoil)

FY语音聊天系统。使用google开源DUI做界面库。boost::asio做网络底层。openal实现语音，opencv实现视频，jpeg压缩。使用mysql数据库。系统实现了用户注册，密码找回，好友上下线提醒，文字语音聊天，视频聊天。(FY voice chat system. Use google to do open source DUI interface library. boost:: asio do network infrastructure. openal voice, opencv for video, jpeg compression. Use mysql database. System to achieve a user registration, password back, to remind friends on the assembly line, text and voice chat, video chat.)

This application tests STL Library.

基于学习的超分辨率重建算法，用C++语言编写，输入多张影像样本进行学习，选择一张低分辨率影像，输出高分辨率影像。Learning based super resolution reconstruction algorithm, using C++ language, input multiple images of the sample to learn, choose a low resolution image, the output of high resolution image.

基于opencv的质心算法,对图片进行图像处理，将彩色图片转为灰度图像，二值阈值化处理，找出图片中目标，运用质心算法求出图像质心。

贝赛尔曲线，可改变控制点变化或者焦点变化
