displaying m images m windows opencv c++

To display multiple images in multiple windows using OpenCV in C++, you can follow these steps:

1. Import the necessary libraries:
2. Include the OpenCV header file: #include <opencv2/opencv.hpp>

3. Include the standard namespace: using namespace cv;

4. Load the images:

5. Use the imread() function to read the images into variables: cpp Mat image1 = imread("image1.jpg"); Mat image2 = imread("image2.jpg"); // Add more images if needed

6. Create windows to display the images:

7. Use the namedWindow() function to create windows for each image: cpp namedWindow("Window 1", WINDOW_NORMAL); namedWindow("Window 2", WINDOW_NORMAL); // Add more windows if needed

8. Display the images in their respective windows:

9. Use the imshow() function to display the images in their respective windows: cpp imshow("Window 1", image1); imshow("Window 2", image2); // Add more images and corresponding windows if needed

10. Wait for user input:

11. Use the waitKey() function to wait for a key press before closing the windows: cpp waitKey(0);

12. Close the windows:

13. Use the destroyAllWindows() function to close all open windows: cpp destroyAllWindows();
