扫描线Zbuffer算法 1。算出模型的包围盒。 2．每条扫描线打点时并不是包围盒内整条线打点，而是先搜索需要刷新的范围， 只是该范围内打点。 (One scan line Zbuffer algorithm. Calculate the model bounding box. 2. Each scan line runs inside the box when not surrounded by the entire line runs, but first need to refresh the scope of the search, but the scope of RBI.)

opengl图形实现，非调用函数直接构图，初级参考学习不错(opengl graphic realization, non-call direct mapping function, the primary reference to learn good)

找待选物体图像的长轴位置(find objects to be elected to the long axis image location)

这是一个简单的程序代码，主要针对hough变化(This is a simple program code, mainly for hough change)

线性反投影算法（Linear Back Projection，简称 LBP）又称累加法，是最早使用的一种简单（ECT图像重建）成像算法。它将通过某点的所有投影射线进行累加，再反向估算出该点的密度值。从成像观点分析，它是不完全的雷登逆变换（完整的雷登逆变换包括微分、希尔伯特变换、反投影和归一化等步骤）。(Linear back projection algorithm (Linear Back Projection, referred LBP), also known as cumulative method, is the first to use a simple (ECT image reconstruction) imaging algorithms. It accumulates all projection rays through a point, then reverse the estimated density value of the point. From the image point of view analysis, it is not exactly the inverse transform Leiden (Leyden complete inverse transformation involving differential Hilbert transform backprojection and normalization steps, etc.).)

3d点云的显示与变深度图，visual C++ 代码(he display and variable depth map of 3D point cloud)

自己写的中值滤波剔野程序，用于信号野值剔除。很简单，其中算法可替换(Write your own wild tick median filtering program for the signal, excluding outliers. Very simple algorithm which can be replaced)

说明：  该代码能实现图像缩放功能，简单，容易理解(The code to achieve the image zoom feature, simple, easy to understand)

对可见光图片的人脸活体判断，内有C++和matlab实现，具体说明详见readme(For the visible light picture of the human face to determine, there are C++ and matlab implementation, specific instructions see readme)
