The ability to see both the faces and the vase require the ability to switch between two possible interpretations, where the images form the “figure” or foreground and the background is the “ground”. This is known as the figure-ground relationship, which allows us to differentiate between objects and their surroundings, and hence, enables us to perceive the faces and the vase from the same image.
