A Psychophysical Investigation of Mechanisms Selective for the Spatial Frequency of Disparity Modulation in Random-Dot Stereograms.
Abstract
The visual system must perform two major functions. The first is resolving spatial layout, and the second is object recognition. Because we live in a three-dimensional (3D) world, these tasks must be performed in three dimensions. That is, the visual system must assess 3D spatial layout and must recognize 3D objects. There are two types of information sources that could be used to perform both functions. Cues of the first type arise directly from characteristics of in the environment. These include shape-from- shading, depth from texture gradients, and motion parallax due to movements of objects in the environment. Cues of the second type arise from characteristics of the observer. These include motion parallax due to movements of the observer through the environment, and binocular disparity due to the relative positions of the two eyes. This paper is concerned with how the visual system processes the last cue: binocular disparity. Specifically, it addresses the visual system's processing of binocular disparity across multiple spatial scales.
