Visual Perception of Structure from Motion

Abstract

The research performed by James Todd during the past year of AFOSR support has examined the ability of human observers to perceive various aspects of a moving object's 3D structure from minimal apparent motion sequences. This research has provided a strong body of evidence that the perceptual analysis of 3D structure from motion is apparently restricted to first order temporal relations. That is to say, when all other factors are optimized, perceptual performance does not improve as the number of discrete frames in an apparent motion sequence is increased beyond two. This research has been accompanied, moreover, by a theoretical analysis of the particular properties of 3D structure that can be computed from first order temporal relations. The analysis makes specific predictions about which tasks can or cannot be performed accurately by human observers, and these predictions are in strong agreement with the psychophysical data.
