Early computation of shape and reflectance in the visual system

Abstract

A COMPELLING sense of three-dimensional shape may be conveyed by the photograph of an object. Cues such as contour, shading, perspective and occlusion, to name a few, contribute to this percept. Psychophysical experiments suggest that certain aspects of three-dimensional shape are computed rapidly and in parallel by the visual system1–7,15. Here we report… (More)
