Kmeans聚类算法的一个示例 是一个简单的程序但是体现了思想(a simple example of K-means algorthm which contains the core thinking method of clustering)

波束形成过程中，滤波器权值固定不变。一旦阵列的几何形状、目标方向确定，其波束模式特性也将确定(In the beamforming process, the filter weights are fixed. Once the array geometry and target direction are determined, the beam pattern characteristics will also be determined.)

fAST FOURIER EXAMPLE

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.
