OpenCV

在OpenCV低版本中，有CvvImage这个类，但是在⾼版本中不再有这个类了，但是当我们需要⽤这个类时，如何添加呢，下⾯是我所总结的⼀些东西，希望对各位有帮助吧。

OpenCv的安装⾃⼰去搞定，我⽤的是OpenCV-2-3-1的版本，使⽤的vs2010

在你的⼯程中添加CvvImage.h和CvvImage.cpp这两个⽂件，⼀般来说此时是编译不能通过的。还需要做下⾯的⼯作：将Intel TBB 3.0⽂件夹复制到D:\\Program Files⽬录下

然后将tbb_debug.dll⽂件复制到D:\\Program Files\\OpenCV-2.3.1-win-superpack\\opencv\\build\\common\bb\\ia32\\vc10⽬录下，

接着在可执⾏⽬录中添加D:\\Program Files\\OpenCV-2.3.1-win-superpack\\opencv\\build\\includeD:\\Program Files\\OpenCV-2.3.1-win-superpack\\opencv\\build\\include\\opencvD:\\Program Files\\OpenCV-2.3.1-win-superpack\\opencv\\build\\include\\opencv2D:\\Program Files\\Intel TBB 3.0\\bin\\ia32\\vc10注意：看你的Opencv安装的⽬录⽽不相同接着需要添加环境变量

如果你是在⽤户模式下，就在⽤户变量的path⾥⾯添加D:\\Program Files\\Intel TBB 3.0\\bin\\ia32\\vc10

如果你是在administrantor模式下，就在系统变量的path⾥⾯添加D:\\Program Files\\Intel TBB 3.0\\bin\\ia32\\vc10最后重新启动，在编译你的⼯程；CvvImage头⽂件[cpp]
