Abstract

A new illusion demonstrating the perception of tilted objects is reported. Physically, all the objects in a rotated image should tilt at the same degree. We, however, found that the tilt of objects in a rotated frame is perceived differently. We tested several objects and found that this phenomenon is especially noticeable when an element in the image has a non-geometric shape. A possible mechanism for this illusion is proposed.
