cuda::GpuMat as input.
If the window was not created before this function, it is assumed creating a window with cv::WINDOW_AUTOSIZE.
If you need to show an image that is bigger than the screen resolution, you will need to call namedWindow("", WINDOW_NORMAL) before the imshow.
@note This function should be followed by a call to cv::waitKey or cv::pollKey to perform GUI
housekeeping tasks that are necessary to actually show the given image and make the window respond
to mouse and keyboard events. Otherwise, it won't display the image and the window might lock up.
For example, **waitKey(0)** will display the window infinitely until any keypress (it is suitable
for image display). **waitKey(25)** will display a frame and wait approximately 25 ms for a key
press (suitable for displaying a video frame-by-frame). To remove the window, use cv::destroyWindow.
@note
[__Windows Backend Only__] Pressing Ctrl+C will copy the image to the clipboard.
[__Windows Backend Only__] Pressing Ctrl+S will show a dialog to save the image.

Parameters:
