How can I use imshow to display multiple images in multiple windows?

Question

I would like to do something like the following in order to display two images on the screen:

imshow("1", img1);
imshow('2', 'img2');

Is it possible to do that?

Answer 1

Yes, it is possible. The function void imshow(const string& winname, InputArray mat) displays an image in the specified window, where -

• winname – Name of the window.
• image – Image to be shown.

The window is identified by its name. So to display two images(img1, img2), in two different window; use imshow with different name like :-

imshow("1",img1);
imshow("2",img2);
