注意，你的代码中的路径要根据OpenCV的具体安装路径做改变。

测试程序

#include

#include

using namespace std;

using namespace cv;

int main(int argc,char*argv[])

{

QCoreApplication a(argc,argv);

const char*imagename="E:\\library\\Pictures\\lena.jpg";

//从文件中读入图像

Mat img=imread(imagename);

//如果读入图像失败

if(img.empty())

{

fprintf(stderr,"Can not load image%s\n",imagename);

waitKey();

return-1;

}

//显示图像

imshow("image",img);

//此函数等待按键，按键盘任意键就返回

waitKey();

return a.exec();

}
