说明：  一个4阶的切比雪夫Ⅰ型低通滤波器，可以用它对信号进行滤波。当然，滤波器的零极点图也是必不可少的。(A 4-order Chebyshev low-pass filter of type Ⅰ, you can use it to filter the signal. Of course, the filter pole-zero map is essential.)

说明：  生成一维云模型的MATLAB程序，简单实用，可以自动生成云模型图片(Generate one-dimensional cloud model MATLAB program, simple and practical, can automatically generate cloud model picture)

基于Harris原理的亚像素角点坐标检测Matlab程序；直接运行click_calib .m文件即可获得亚像素级角点坐标，附录Ⅱ中的其它函数文件均会被click_calib .m文件调用。(Based on the principle of subpixel Harris corner coordinates detection Matlab procedures run directly click_calib. M file to obtain sub-pixel corner coordinates, Appendix Ⅱ other functions in the file will be click_calib. M file called.)
