How to delete drawn objects with OpenCV in Python?
Have a method or something that when it's executed, will replace the image with stuff drawn on it with an original unaltered image. It's best to create a clone of your original image to draw on.
How to delete drawn objects with OpenCV in Python ?

I draw objects on click (cv2.rectangle, cv2.circle) ...
Then I would like to delete only drawn objects.
I know that i need to make a layer in behind of the real image and to draw on another one.
But I do not know how to implement this in code.
