这是一个关于全局的人工鱼群算法的例子，适合初学者学习。(This is an example of global AFSA, for beginners to learn.)

一系列Matlab的m文件的打包，包括Hurst等(A series of Matlab m-file package, including Hurst, etc.)

a band pass signal through an ideal BPF x(t) =[1+cos(pi*t/T)]*cos(2pi*fc*t)

利用matlab实现fir滤波器的源程序(Realize fir filter using matlab source)

VBLAST源代码！ 下载后将.rar去掉，即可！ 文件也可用ultraedit等软件直接打开(VBLAST source code! After downloading. Rar removed can be! Documents available ultraedit software directly open)

是对巴特沃斯滤波器设计的详细讲述，对于初学者有很好的帮助。我觉得比较实用。(Butterworth filter design is described in detail for the beginners have a good help. I think the more practical.)

Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.
