(1) Debug Realse 区别：
Debug 环境下用来调试代码 发现bug 代码运行速度慢
Realse 环境下用来测试程序的效率
(2) VS2010+opencv 2.4.11 属性配置
主要是三个地方的属性配置
a. 在Debug和Release 情况下 VC++目录 下的包含目录和库目录配置是一样的 主要是指出你的opencv的安装路径（下图是我安装的opencv路径）如下图
b.链接器里面的输入设置 Debug情况下 输入的lib名的最后一个字母是d
如在我安装的opencv 2.4.11 Release 情况下
opencv_calib3d2411.lib
opencv_contrib2411.lib
opencv_core2411.lib
opencv_features2d2411.lib
opencv_flann2411.lib
opencv_gpu2411.lib
opencv_highgui2411.lib
opencv_imgproc2411.lib
opencv_legacy2411.lib
opencv_ml2411.lib
opencv_objdetect2411.lib
opencv_ts2411.lib
opencv_video2411.lib
Debug 情况下：
opencv_calib3d2411d.lib
opencv_contrib2411d.lib
opencv_core2411d.lib
opencv_features2d2411d.lib
opencv_flann2411d.lib
opencv_gpu2411d.lib
opencv_highgui2411d.lib
opencv_imgproc2411d.lib
opencv_legacy2411d.lib
opencv_ml2411d.lib
opencv_objdetect2411d.lib
opencv_ts2411d.lib
opencv_video2411d.lib
