Visual Perception of 3-Dimensional Form from Different Types of Optical Deformations.

Abstract

The research performed during the past three years of AFOSR support has examined the abilities of human observers to determine an object's 3-D form from various types of optical information such as shading, texture, motion, binocular disparity, both individually and in combination. The results of this search provide strong evidence that our perceptual representations of 3-D metrical properties are surprisingly inaccurate and imprecise, but that observers are quite good at judging ordinal or nominal relations among different surface regions. We have also examined how these judgments are influenced by combining different types of optical information using both computer simulations and direct viewing of natural scenes.
