MECHANISMS FOR
MOTION PERCEPTION
BY EDWARD ADELSON
ne of the goals of vision science is to understand
the workings of visual systems from the diverse
perspectives of psychophysics, neurophysiol-
ogy, and computation, and to develop this un-
derstanding into an integrated theory of vision. This pro-
gram has been particularly successful in the study of motion
perception.
Let us begin by considering one of the long-standing
problems of motion perception: the phenomenon of appar-
ent motion, by which a rapid sequence of movie frames
gives rise to the impression of motion. For many years, this
was a hotly debated phenomenon. But recently a unified
view has emerged that combines insights from several
converging lines of investigation. In this view, motion is
conceptualized as a kind of slant or orientation in space-
