title: Motion vision: are 'speed lines' used in human visual motion?
abstract: Motion analysis poses problems for any visual system, not least because of the ambiguities inherent in motion signals. Recent studies suggest that the human motion system may exploit 'motion streaks' - analogous to the cartoonist's speed lines - to help resolve the direction of ambiguous motion.
