VC++程序从OpenCV2.1迁移到OpenCV2.2（vs2010+OpenCV2.2+windows7设置）

    目前发布的OpenCV的版本为2.2，比之前的2.1版本有很大的改动，有很多程序的迁移遇到了一些问题，现将遇到的一些问题归纳一下：

    1）opencv下载：http://sourceforge.net/projects/opencvlibrary/files/

         opencv wiki：http://opencv.willowgarage.com/wiki/

         其中官方主页提供下载最新的 2.2 for vs2010 已编译版本

    2)  opencv2.2 环境设置

 

         a. windows环境变量path： D:/Program Files/OpenCV2.2/bin         b. vs2010在每个单目项目属性:

              linker -->input：

                 opencv_core220d.lib;opencv_highgui220d.lib;opencv_calib3d220d.lib;

                 opencv_contrib220d.lib;opencv_features2d220d.lib;opencv_ffmpeg220d.lib;

                 opencv_imgproc220d.lib;opencv_video220d.lib;opencv_ml220d.lib;

                 opencv_legacy220d.lib

               vc++目录：                   包含目录：./DirectShow/include;D:/Program Files/OpenCV2.2/include/opencv;D:/Program Files/OpenCV2.2/include                   库目录： D:/Program Files/OpenCV2.2/lib

     3）在opencv2.2版本中除了对一些库做了很大改动意外，还有一个很重要的类CvvImage类被取消了。在很多在早期版本中很多MFC程序利用CvvImage类，将图片或视频显示在窗口上就会报错。解决这个问题就需要将CvvImage类手动添加到你的程序中，如下：

         a：将CvvImage.h头文件加入到你的程序“头文件”中

         b：将CvvImage.cpp类文件加入到“源文件”中

         最后在vs2010主文件.cpp中，加入 #include "CvvImage.h" 即可。CvvImage类就可以在你的程序中使用。
