粒子群优化算法是一种基于种群的随机优化算法…
Particle swarm optimization (PSO) is a population based stochastic optimization technique developed by Dr. Eberhart and Dr. Kennedy in 1995, inspired by social behavior of bird flocking or fish schooling. Each particle keeps track of its coordinates in the problem space which are associated with the best solution (fitness) it has achieved so far. (The fitness value is also stored.)
This value is called pbest. Another "best" value that is tracked by the particle swarm optimizer is the best value, obtained so far by any particle in the neighbors of the particle. This location is called lbest. when a particle takes all the population as its topological neighbors, the best value is a global best and is called gbest. Following is the steps of PSO:

"电工学"是高等院校工科的一门技术基础课程,由于它具有课时数多、内容覆盖面广、课程理论性强和内容抽象等特点,学生普遍认为其枯燥难学。针对这些特点,本文提出了在该课程讲授中将比较和控制思想融于理论教学。结合学生对知识的掌握情况,采取不同的教学方式,采用任务驱动式教学形式将理论教学与实验教学相结合。最后,对如何合理运用多媒体和网络辅助教学进行了讨论,并将其成功地应用于理论课程教学中。-" Electrical Engineering" is the institutions of higher learning in a technology-based engineering courses, because it has more than a few hours, covering a wide range of curriculum and content of the abstract theory with strong characteristics, the students generally felt that its boring difficult to learn. In response to these characteristics, this paper will be taught in the course to compare and control the thinking should be integrated in the theory of teaching. With the students of knowledge to grasp the situation, adopt a different teaching methods, using task-driven forms of teaching the theoretical combination of teaching and experimental teaching. Finally, how reasonable the use of multimedia and network-assisted instruction were discussed, and successfully applied to the teachi

yuv视频采集和显示
嵌入式视频采集软件需要实现视频流的采集，视频显示，利用V4L2（video
for linux2）、FrameBuffer提供的应用程序接口实现，需要对摄像头、显示屏进行操作。USB摄像头、LCD显示屏都属于字符设备，分别为/dev/video0、/dev/fb0文件。本代码即利用这些基本知识实现视频采集

VFW视频检测
现在在vc上采集视频常用的方法有三：vfw，directshow，opencv ；今天我们首先做一下利用vfw的视频采集程序。
VFW(Video for Windows)是Microsoft推出的关于数字视频的一个软件开发包，VFW的核心是AVI文件标准。AVI(Audio Video Interleave)文件中的音、视频数据帧交错存放。围绕AVI文件，VFW推出了一整套完整的视频采集、压缩、解压缩、回放和编辑的应用程序接口(API)。由于AVI文件格式推出较早且在数字视频技术中有广泛的应用，所以VFW仍然有很大的实用价值，而且进一步发展的趋势。
在VC++开发环境中调用VFW和使用其它开发包没有什么不同，只是需要将VFW32.lib文件加入工程中，但在开放视频捕捉与压缩管理程序时需要其它软件硬件设置。VFW为AVI文件提供了丰富的处理函数和宏定义，AVI文件的特点在于它是典型的数据流文件，它由视频流、音频流、文本流组成。所以对AVI文件的处理主要是处理文件流。
