Abstract :
Diorama artists produce a spectacular 3D effect in a confined space by generating depth illusions that are faithful
to the ordering of the objects in a large real or imaginary scene. Indeed, cognitive scientists have discovered that
depth perception is mostly affected by depth order and precedence among objects. Motivated by these findings,
we employ ordinal cues to construct a model from a single image that similarly to Dioramas, intensifies the depth
perception. We demonstrate that such models are sufficient for the creation of realistic 3D visual experiences.
The initial step of our technique extracts several relative depth cues that are well known to exist in the human
visual system. Next, we integrate the resulting cues to create a coherent surface. We introduce wide slits in the
surface, thus generalizing the concept of cardboard cutout layers. Lastly, the surface geometry and texture are
extended alongside the slits, to allow small changes in the viewpoint which enriches the depth illusion.
