给定一个图像，其中包含足够的信息来计算地平面消失线和垂直消失点，以及一个已知高度的物体。然后，只要他们的头部和脚都可见，就可以在场景中的任何地方测量站在地平面上的人的高度。(Given an image which contains sufficient information to compute the ground plane vanishing line and the vertical vanishing point, and also one object of known height for which the top and base are imaged. Then the height of a person standing on the ground plane can be measured anywhere in the scene provided that their head and feet are both visible.)

该程序是一个用IDL将多个图形绘制在同一个窗口中的实例程序，对初学者很有用(This program is a idl program which plot multiple image in the same window, It is important to new study.)

光斑的中心提取：重心法和圆拟合。先用多次迭代求阈值并且对图像二值化，再用重心法和圆拟合提取光斑中心。(light spot method：median point ，circle fitting)

基于matlab三维重建代码，及基础知识的了解和掌握(three-dimensional reconstruction)

说明：  水平集（level set）中快进算法（fast marching）算法的matlab工具箱，内容很全面。(Level Set (level set), Fast Forward algorithm (fast marching) algorithm m atlab Toolbox, which is very comprehensive.)

在matlab开发环境中，基于8近临的贴标签算法，实现不同连通域的区分(In the Matlab development environment, based on eight nearly labeling algorithm to achieve the distinction of different Unicom domain)

这个程序是用来绘制光子晶体光纤的色散曲线。(This program is used to draw the dispersion curves of the photonic crystal fiber.)

说明：  给出一些离散的点，根据最小二乘法求出拟合的直线。(If there are some discrete points, you can get a line based on least square method.)

说明：  几何偏微分方程方法应用于曲线演化的一个小程序，这里是一个matlab的源程序，不是十分复杂，显示了一个哑铃形状的曲线演化的过程(geometric partial differential equations method has been applied to the evolution of the curve of a small program here is a source of Matlab, is not very complex, and shows a dumbbell-shaped curve of the evolutionary process)

说明：  c++的绘制二维等值线源码。有示例数据，可以运行。(c++ two-dimensional contour map of the source。c++ code for contour map)
