Abstract
Two differently oriented moving gratings when superimposed, are often seen to move coherently in a direction quite different from that of either grating's. By varying the characteristics of the component gratings researchers have been able to study specific aspects of the motion processing mechanisms in the primate visual system. Here we report the results of experiments performed with a class of subjective gratings. We find that observers perceive coherence and are able to accurately report pattern velocity with our stimuli. These results have implications for some key issues concerning strategies and mechanisms for motion estimation in the human visual system. Copyright © 1996 Published by Elsevier Science Ltd.
