| Abstract |
|
In a popular visual illusion, the portrait on paper
currency is folded into an M shape along vertical lines
through the nose and the eyes. When this folded
picture is tilted back and forth horizontally the face
undergoes striking changes in expression. This
distortion reveals two insights concerning 3D
representation in the human visual system and we have
explored these with experiments on simple schematic
faces and observations on distortions of laser range
images of faces. The observations show first that when
recovering depicted depth, pictorial cues are interpreted
independently of binocular depth information and
second, that the recovery of facial expression is based
on a scaled prototypical face structure.
