Visual mechanisms of motion analysis and motion perceptionTools Derrington, Andrew, Allen, Harriet A. and Delicato, Louise (2003) Visual mechanisms of motion analysis and motion perception. Annual Review of Psychology, 55 . pp. 181-205. ISSN 1545-2085 Full text not available from this repository.AbstractPsychophysical experiments on feature tracking suggest that most of our sensitivity to chromatic motion and to second-order motion depends on feature tracking. There is no reason to suppose that the visual system contains motion sensors dedicated to the analysis of second-order motion. Current psychophysical and physio- logical data indicate that local motion sensors are selective for orientation and spatial frequency but they do not eliminate any of the three main models—the Reichardt de- tector, the motion-energy filter, and gradient-based sensors. Both psychophysical and physiological data suggest that both broadly oriented and narrowly oriented motion sensors are important in the early analysis of motion in two dimensions.
