ABSTRACT
Impossible figure is a figure which looks realizable at first glance, but is not actually realizable as perceived by the human eyes. Optical illusion object is a three dimensional object made to be an impossible figure when viewed from a specific viewpoint. The viewpoint that realizes an optical illusion is called as an illusion viewpoint. An optical illusion object is not perceived as an impossible figure when a viewpoint moves away from an illusion viewpoint.

Animating impossible figure from twisted torus to penrose stairs
SA '13: SIGGRAPH Asia 2013 PostersWhen a start prism and an end prism's vertices are in the same values on the projection screen, the shape model is viewed as an impossible figure. Therefore, if we can create the optical illusion object according to an arbitrary viewpoint, it is ...
A depth perception and visual comfort guided computational model for stereoscopic 3D visual saliency
With the emerging development of three-dimensional (3D) related technologies, 3D visual saliency modeling is becoming particularly important and challenging. This paper presents a new depth perception and visual comfort guided saliency computational ...
