Question

Answer 1

The cv2.imshow() function always takes two more functions to load and close the image. These two functions are cv2.waitKey() and cv2.destroyAllWindows(). Inside the cv2.waitKey() function, you can provide any value to close the image and continue with further lines of code.

    # First line will provide resizing ability to the window
    cv.namedWindow('Amanda', cv.WINDOW_AUTOSIZE)

    # Show the image, note that the name of the output window must be same
    cv.imshow('Amanda', img)

    # T0 load and hold the image
    cv.waitKey(0)

    # To close the window after the required kill value was provided
    cv.destroyAllWindows()

Hoping that you will get the image in a separate window now.
