说明：  二维数字图像相关算法，可实现亚像素精度的匹配和应变测量(Two dimensional digital image correlation algorithm, which can achieve sub-pixel precision matching and strain measurement)

绘制原图像和加密图像R、G、B三通道的水平、垂直、对角相关性，以及R、G、B的直方图(Draw the horizontal, vertical and diagonal correlation of the original image and the encrypted image in R, G and B, and the histogram of R, G and B.)

这些程序是关于因子图及和积算法的基础程序，对入门有用(These programs are the basic procedures for factor diagrams and accumulation methods, which are useful to the introduction.)

说明：  这是DB2错误码，在SQL语句使用中会出现错误，就可以查找这些错误码及时解决问题(This is the DB2 error code. If there are errors in the use of SQL statements, you can find these error codes and solve the problem in time.)

说明：  lastools工具，利用lastools工具可以將las文件轉換類型，並且可以在potree中使用(the tool of lastools)

本微信小程序主要是让编程者学习这种微信小程序的编写方法，根据单选题的编写方法，写出的模拟驾照考试的界面和功能，在考生选择答案后会自动换题进入下一题等，界面如图所示，与驾照考试软件的界面风格似乎挺像。

这款CSS3应用是一个倒计时插件，这款倒计时插件的外观还是比较简单大气的，加上阴影，有着3D立体的视觉效果。倒计时标有天、时、分、秒，我们可以很清晰的看出时钟的走动。我们可以将它制作成挂件放到自己的个人博客上去，来实现活动开始的倒计时功能。(This CSS3 application is a countdown plug-in, the countdown plug-in appearance is relatively simple atmosphere, coupled with shadows, has a 3D stereoscopic visual effect. The countdown is marked by days, hours, minutes and seconds, and we can clearly see the movements of the clock. We can make it into a pendant on our personal blog to achieve the countdown function of the beginning of the event.)
