Opencv2.3.1中：每新建一个项目必做的，选择“Debug”，在“附加依赖项”那栏点击右边的“编辑”按钮，复制下面的库文件名到上方空白处： opencv_calib3d231d.lib opencv_contrib231d.lib opencv_core231d.lib opencv_features2d231d.lib opencv_flann231d.lib opencv_gpu231d.lib opencv_highgui231d.lib opencv_imgproc231d.lib opencv_legacy231d.lib opencv_ml231d.lib opencv_objdetect231d.lib opencv_ts231d.lib opencv_video231d.lib （可根据实际需要删减） 然后，在“配置”下拉框中选择“Release”，照上面的操作，复制下面的库文件名到上方的空白处： opencv_calib3d231.lib opencv_contrib231.lib opencv_core231.lib opencv_features2d231.lib opencv_flann231.lib opencv_gpu231.lib opencv_highgui231.lib opencv_imgproc231.lib opencv_legacy231.lib opencv_ml231.lib opencv_objdetect231.lib opencv_ts231.lib opencv_video231.lib 例2-1显示照片 #include stdafx.h #include opencv2/opencv.hpp using namespace std; using namespace cv; int main(int argc, char* argv[]) { const char* imagename = woheadai.jpg; //从?¨?文?件t中D读¨￠入¨?图a?像?
