在最新的OpenCV3.1.0中，众多著名的特征检测算子（如SIFT, SURF, ORB算子等）都被移除了，这些算子都被移到了opencv_contrib库中，另外，这个库中还有很多有意思的模块（如ArUco，dnn等）值得我们学习使用。要想使用这些库，就要到OpenCV的github下载源码编译。这个过程还是有些费事的，如果想一步步做请看
这篇博客
。
如果想省事的话可以直接下载本篇博客下面编译好的库来使用（注意只适用于OpenCV3.1.0）。
下面讲一下具体配置步骤：
vs工程包含目录：
…\install\include
…\install\include\opencv
…\install\include\opencv2
库目录：
…\install\x64\vc14\lib
…\install\x64\vc14\lib

系统环境变量Path：在最后加上…\install\x64\vc14\bin
然后需要重启一次vs，否则好像只能编译不能运行
配置好后可以用下面的代码测试一下。下面是运行结果：
