在C++中使用OpenCV顯示圖像的問題

Question

我希望使用C++ OpenCV代碼顯示圖像。下面是代碼片段：

//Load image 
Mat img = imread("Example1.jpg"); 

//Display in window 
namedWindow("Skin"); 

//display image 
imshow("Skin",img); 

//returns the matrix size 
cout<<img.size()<<endl; // wrong 

請幫助如何顯示大小。我曾多次嘗試購買失敗。

Answer 1

//Load image 
Mat img = imread("Example1.jpg"); 

//Display in window 
namedWindow("Skin"); 

//display image 
imshow("Skin",img); 

//returns the matrix size 
cout << "width= " << img.cols << " height= " << img.rows<< endl; 
//OR if you wanna use the size() getter. 
cout << "width= " << img.size().width << " height= " << img.size().height << endl;
