Accurate visual measurement of three-dimensional moving patterns

J S Lappin et al. Science. .

Abstract

Human observers discriminated relative three-dimensional distances in simple patterns of motion parallax with an acuity similar to vernier acuity under comparable conditions. Accurate visual measures of three-dimensional distance can be derived from the structural invariance of patterns undergoing perspective transformations.
