The research performed by James Todd during the past three years of AFOSR support has examined the abilities of human observers to determine an objects 3-dimensional form from various types of optical information such as shading, texture, motion or binocular disparity, both individually and in combination. The results of this research provide strong evidence that our perceptual representations of 3D 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 judgements are influenced by combining different types of optical information using both computer simulations and direct viewing of natural scenes.
