Question

我试图通过导入opencv运行基本程序以在C ++上显示图像。它正在导入“ #includes opencv2 / opencv.hpp”，但是在声明MAT类时出现错误。

我是C ++的新手，所以将不胜感激。

代码：

#include <iostream>
#include <opencv2/opencv.hpp>

using namespace std;
using namespace cv;

int main(){
    MAT img = imread("FacialBloodVessels.jpg"); //"FacialBloodVessels.jpg" name of file
    namedWindow("image", WINDOW_NORMAL); 
    imshow("image", img); //display the image imported
    waitKey(0);
    return 0 ;
}

错误的构建控制台：
