The nonius horopter. I. History and theory.
TLDR
It is emphasized that the leap from entoptic geometry to phenomenal externality cannot be made quite so simply as the reliabilities of frontal plane and of equidistant horizon judgements might in themselves lead us to believe.About:

Journal ArticleDOI
Systematic distortions of shape from stereopsis
TL;DR: The results strongly suggest that the observed shape distortions are a consequence of scaling horizontal disparities with an incorrect measure of egocentric distance.
Journal ArticleDOI
Globality and stereoscopic fusion in binocular vision.
TL;DR: Two central problems are dealt with in the paper: How is it possible for the binocular visual system to detect the correct disparity in repeating patterns such as computer-generated random-dot stereograms?
Journal ArticleDOI
The induced effect, vertical disparity, and stereoscopic theory
Barbara Gillam,Bo Lawergren +1 more
TL;DR: The induced effect is shown to be an appropriate stereoscopic response to a zero horizontal disparity surface at the eccentricity indicated, however, since extraretinal convergence signals provide conflicting evidence about eccentricity, they may attenuate the induced effect from its mathematically predicted value.
Journal ArticleDOI
A neurophysiological determination of the vertical horopter in the cat and owl.
TL;DR: A determination of the vertical horopter in two species is undertaken by simultaneously mapping the receptive field positions of binocular cortical neurons at various elevations along the zero azimuthal meridians.
Journal ArticleDOI
The surface of the empirical horopter
TL;DR: The Hering-Hillebrand deviation and the Helmholtz shear of horizontal disparity exist throughout the visual field and the combination of points in space and binocular eye position that minimizes the disparity between stimulated points on the retinas and the empirical corresponding points is found.

TL;DR: A composite thin film resistor is disclosed, including an electrically inert substrate upon which is deposited a nickel-chromium alloy thin film, and an overlying second thin film - which is initially deposited as metallic tantalum - which provides a very high degree of environmental protection with respect to the Ni-Cr film.
Journal ArticleDOI
The neural mechanism of binocular depth discrimination
TL;DR: Binocularly driven units were investigated in the cat's primary visual cortex in a bid to understand why cats have good night vision and why cats with poor vision have poor daytime vision.

Contributions to the Physiology of Vision. Part the First. On Some Remarkable, and Hitherto Unobserved, Phenomena of Binocular Vision
TL;DR: There is no difference between the visual appearance of an object in relief and its perspective projection on a plane surface; and hence pictorial representations of distant objects, when those circumstances which would prevent or disturb the illusion are carefully excluded, may be rendered such perfect resemblances of the objects they are intended to represent as to be mistaken for them.
