基于人群分类的SEIR模型的仿真，得出模型中各参数(传播率，等)对谣言传播范围的影响(Simulation of SEIR model based on crowd classification)

说明：  图像色彩空间转换，hsi空间，cmy，yiq，yuv等等(Digital Image Color Space Conversion)

常用的几个图像二值化算法，包括全局的二值化和局部的二值化算法(This program contains Several commonly used image binary algorithms including global and local binary algorithms.if you want ,just download)

用于pivlab处理得到的流场数据画图，具体使用见注释(Flow field data plots for piv processing)

说明：  多尺度多方向性的剪切波Shearlet变换优于小波变换，里面包含很多例子，可以直接运行，可以用于图像去噪，分割，增强等，是一个优于小波的图像稀疏表示工具(Shearlet transform of multi-scale and multi-directional shear wave is better than wavelet transform. It contains many examples and can run directly. It can be used for image denoising, segmentation and enhancement. It is an image sparse representation tool better than wavelet transform.)

以python语言为平台，对机载激光雷达原始数据Las格式和txt格式进行读取，并根据信息熵确定维度特征计算的最佳邻域半径，最后计算得到最佳邻域半径和最佳维度特征值(Based on Python language, the Las format and TXT format of airborne lidar raw data are read, and the optimal neighborhood radius is determined according to the information entropy. Finally, the optimal neighborhood radius and the optimal dimension eigenvalue are calculated.)

简单实现画矩形和缺角的矩形，并且实现矩形的缩放和移动(Simple to draw a rectangle and the missing corner of the rectangle, and the rectangle zoom and move)

实现热键截图的功能，把截到的图片保存到制定的文件夹中，然后把图片输出到报表中，形成报表！(Achieve hotkey screenshot function, the cut-off to save the picture to develop a folder, and then the picture output in the report, the formation of statements!)

这是一个相机标定程序，有数据检验，求出两个相机的投影矩阵，用于双目视觉(This is a camera calibration procedures, test data, obtained two camera projection matrix for the binocular vision)

本代码主要关于摄影测量中的单向空间后方交会(resection of photogrammetry)
