运动检测

Haarcascade用于检测眼睛、鼻子、嘴巴和opencv。 ；已测试。非常有效好吧，是的在haar-like中使用旧的opencv格式。

只需要将你需要导入的视频替换原来的视频，运行即可实现目标检测与跟踪，但还需要自己配置好环境，本人是用opencv3.0.0和visual studio 2013环境下运行的，运行稍微调动滚动条。

利用最简单的帧差法检测目标，基于opencv库，前后帧图像作差得到前景图像，然后设置阈值，进行二值分割，另外代码中还可以选用大津法进行自动阈值分割。得到的结果可以利用方框进行框选出来

说明：  通过knn分类算法识别魔方的色块颜色，加入是否识别成功判断，成功识别率比阈值法识别更高。有完整的备注(Through the KNN classification algorithm to identify the color block of the cube, the success rate is higher than the threshold method. Code has complete comments)

基于opencv开源库，改善图像的对比度和亮度，速度快，效果好

说明：  手动选择三对特征点，标注特征点，实现二维图像的仿射配准；每完成一对需要按Q键进行下一对；平台是Spyter(Radiation registration by labeling feature points)

基于OpenCV和FFTW实现的相位相关图像匹配程序，需要OpenCV和FFTW库文件的支持。本程序并没有用到OpenCV中的DFT，而是用了FFTW中的FFT，所以速度要快很多。(Based on OpenCV and the FFTW implementation phase correlation image matching procedures, require OpenCV and FFTW library files. This procedure does not use OpenCV in the DFT, but with the FFTW in the FFT, so much faster.)

本文主要介绍下opencv中怎样使用hog算法，因为在opencv中已经集成了hog这个类。其实使用起来是很简单的，从后面的代码就可以看出来。本文参考的资料为opencv自带的sample。 　　开发环境：opencv2.4.2+Qt4.8.2+ubuntu12.04+QtCreator2.5. 　　实验功能： 　　单击Open Image按钮，选择需要进行人检测的一张图片，确定后自动显示出来。该图片的大小没限制。 　　单击People Detect按钮，则程序会自动对该图片进行行人检测，且将检测到的效果显示出来，即用1个矩形框将行人框出来。 　　单击Close按钮，退出程序。(This article describes how to use the next opencv the hog algorithm has been integrated in the opencv hog this. In fact, it is easy to use, can be seen from the code behind. Reference information in this article comes with sample for opencv. Development environment: opencv2.4.2+Qt4.8.2+ubuntu12.04+QtCreator2.5 experimental feature: Click the Open Image button to select a picture of the need for people detection, to determine automatically displayed. No limit on the size of the picture. Click the People Detect button, the program automatically the picture of pedestrian detection, and the detected results show a rectangular box, pedestrian box out. Click the Close button to exit the program.)

说明：  基于OpenCV和分水岭算法，对电路板进行缺陷检测。效果还可以，提供给大家学习。(Based on OpenCV and watershed algorithm, defect detection of circuit board is carried out. The effect is OK, for everyone to learn.)

在opencv+VS2013平台上实现hough变换算法，可以检测边缘、直线等等
