STEREO CAPTURE - LOCAL REMATCHING DRIVEN BY BINOCULARLY ATTENDED 3-D CONFIGURATION RATHER THAN RETINAL IMAGES

Previous explanations for stereo capture were mainly based on the low- level perceptual processing of binocular stereopsis which usually show s that one pair of retinal images corresponds to only one 3-D perceptu al configuration. Stereo capture, however, may encounter multiple perc eptual configurations due to the matching ambiguity of wallpaper eleme nts that may not be solved merely by bottom-up processing of the retin al stimuli. The present study suggests that binocular attention plays an important role in stereo capture by way of selecting and enhancing a perceptual configuration that is often ambiguous without attention i nvolved. Stereo capture results from wallpaper's local rematching driv en by binocularly attended 3-D configuration rather than retinal image s. (C) 1998 Elsevier Science Ltd. All rights reserved.
