How to get image width and height in OpenCV?
Question:
I want to get image width and height, how can I do that in OpenCV?
For example:
Mat src = imread("path_to_image");
cout << src.width;
Is that right?
Answers:
You can use rows and cols:
cout << "Width : " << src.cols << endl;
cout << "Height: " << src.rows << endl;
or size():
cout << "Width : " << src.size().width << endl;
cout << "Height: " << src.size().height << endl;
or size
cout << "Width : " << src.size[1] << endl;
cout << "Height: " << src.size[0] << endl;
Also for openCV in python you can do:
img = cv2.imread('myImage.jpg')
height, width, channels = img.shape
