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<QtCore/QCoreApplication>
#include<opencv.hpp>
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();
}。
