这个事关于Computer Graphics （计算机图形学）的教学代码！！！(The thing about Computer Graphics (computer graphics) teaching the code! ! !)

检测图形中的直线，在程序中稍微改动，即可检测多条直线(Detection of graphics in a straight line, a slight change in the procedure, can detect more than a straight line)

关于车辆跟踪的c++程序，使用了opencv进行跟踪，采用了帧差方法效果还不错(vehicle detection)

请将本压缩文件包下的所有文件放在AutoCAD的支 持目录之下，如 AutoCAD 的安装目录下；或者在下拉 菜单中的 工具-> 选项 －> 文件 -> 支持文件搜索路 径 -> 添加 本程序所在目录。调入应用程序jgj.vlx ， 可以直接将本程序拖入AutoCAD绘图区域，或者在下拉 菜单的 工具－>加载应用程序 中找到本程序后加载即 可! 成功加载后，在命令行内输入bzjgj即可运行。在 对话框中,可以选择螺栓螺母的类型以及其它平、弹垫、 螺纹的显示等，具体使用方法可参见本文件夹中的图片。 体验版只能绘制规格为M10之组件,如果您要注册本工 具,可在命令行内输入 zc ,即可获得相关注册信息。(Please support all the compressed files in AutoCAD package under the Held under the directory, such as AutoCAD installation directory or pull-down Menu Tools-> Options-> File-> Support file search path Path-> add the program directory. Transferred to the application jgj.vlx, This program can be directly dragged into the AutoCAD drawing area, or in the drop-down Menu Tools-> Load application found that after loading the program Can! After successfully loaded in the command line, type bzjgj to run. In Dialog box, you can select the type of bolts and nuts and other flat, spring washers, Threaded display, specific methods can be found in the folder of pictures. Trial version can only draw specifications for the components of the M10, if you want to register the workers Tools, you can enter in the command line zc, you can get the relevant registration information.)

实现摄影测量中空间后方交会的问题，用以求得像片的内外方位元素(To achieve space resection in photogrammetry issues photograph to obtain the internal and external orientation elements)

VC图象处理电子书，Chm格式，基本与位图相关的都作了说明，很不错(VC image processing e-books, Chm format, and basic bitmap were made related to the note, a very good)

3D 点云建筑物分割代码3D 点云建筑物分割代码3D 点云建筑物分割代码(3D point cloud, buildign segmentation3D point cloud, buildign segmentation3D point cloud, buildign segmentation)

图像的相关系数是衡量两幅图像的相关程度的，本代码直接通过选定区域计算出相关系数！(image correlation coefficient is a measure of two images of the code directly through selected regional correlation coefficient calculated!)

光流算法的源码 运用稠密光流（Lucas-Kanade）算法跟踪运动的图像(Optical flow algorithm source code using dense optical flow image (Lucas-Kanade) algorithm to track the movement of)

超像素分割方法，在计算机视觉领域，图像分割（Segmentation）指的是将数字图像细分为多个图像子区域（像素的集合）（也被称作超像素）的过程。超像素有一系列位置相邻且颜色、亮度、纹理等特征相似的像素点组成的小区域。这些小区域大多保留了进一步进行图像分割的有效信息，且一般不会破坏图像中物体的边界信息。(Super pixel Segmentation method, in the field of computer vision, image Segmentation, Segmentation) refers to the digital image Segmentation region for multiple image sequence (the set of pixels) (also known as the pixels) process. Adjacent pixels have a series of position and features such as color, brightness, texture similar to that of small region composed of pixels. Most of these small area retains the further effective information for image segmentation, and generally does not destroy the boundary of the object in the image information.)
