一开学就搞实训，还是没学过的图像处理。痛苦啊！图像处理时一般使用Matlab中的图像工具箱，或者是C/C++和OpenCV结合使用。以前看过一些关于opencv的文章，没想到现在要用上了。
把搭建开发环境的过程分享一下
一、首先假设已经安装了Visual studio 2012 。然后下载 opencv 2.46 ，点击exe解压文件到指定的目录。我的在”E:Program Filesopencv"目录下。
然后添加环境变量PATH
1 E:Program Filesopencvuildx86vc11in; 2 E:Program Filesopencvuildx86vc11lib;
2.打开visual studio 2012，新建win32控制台应用程序，如ImageDisplay如图
3.在ImageDisplay属性页上右键添加包含目录和库目录两项。分别为：
包含目录：
1 E:Program Filesopencvuildinclude 2 E:Program Filesopencvuildincludeopencv 3 E:Program Filesopencvuildincludeopencv2
库目录：
E:Program Filesopencvuildx86vc11lib
如下图所示：
4.然后点击连接器，添加附加依赖项：配置Debug属性-》链接器-》输入-》附加依赖项
opencv_calib3d246d.lib;opencv_contrib246d.lib;opencv_core246d.lib;opencv_features2d246d.lib;opencv_flann246d.lib;opencv_gpu246d.lib;opencv_haartraining_engined.lib;opencv_highgui246d.lib;opencv_imgproc246d.lib;opencv_legacy246d.lib;opencv_ml246d.lib;opencv_nonfree246d.lib;opencv_objdetect246d.lib;opencv_ocl246d.lib;opencv_photo246d.lib;opencv_stitching246d.lib;opencv_superres246d.lib;opencv_ts246d.lib;opencv_video246d.lib;opencv_videostab246d.lib
4.保存后，大功告成！运行，就得到阿狸头像啦
