The perception of form and motion
Current Opinion in Neurobiology, 1993Although form and motion are two distinct aspects of visual processing, they do not start as separate entities in the visual system. Early analyses extract discontinuities in various image attributes and these can trace the outline of a form. When displaced, the same image features can give rise to impressions of motion. Recent work has overturned many

The notion is ubiquitous in film literature.

Extracting a motion signal for a two-dimensional contour requires the human visual system to derive a velocity vector from the spatially limited receptive fields of motion sensitive cortical cells. An individual cell's response may not specify the contour's true velocity.
