Binocular depth perception without geometrical cues
TLDR
Binocular depth perception arising from stereoscopic presentation of two gratings of different spatial frequencies is investigated and a model is proposed for a mechanism of stereoscopic depth perception based on the comparison of spatial frequency content in the two retinal images.About:

Depth perception in disparity gratings
TL;DR: Tilt is perceived from gratings of the same spatial frequency but differing in contrast by 50% or more, and these phenomena are not easy to explain on the basis of disparities at corresponding retinal points, but seem to require more global processing of the whole image.
Journal ArticleDOI
A second neural mechanism of binocular depth discrimination
TL;DR: Rotation of an object about its horizontal axis, towards or away from the viewer's eyes, usually causes the images of its contours to have slightly different orientations on the two retinae.

Interocular differences in contrast and spatial frequency: effects on stereopsis and fusion.
Clifton M. Schor,Thomas Heckmann +1 more
TL;DR: Stereothresholds appear to be elevated by binocular suppression evoked by interocular differences in contrast, predicted from positional disparities between edge features rather than from differences in spatial frequency.

On utrocular discrimination
Randolph Blake,Robert H. Cormack +1 more
TL;DR: In this article, a forced-choice procedure was used to determine which eye received sine-wave grating patterns in a two-category forcedchoice procedure, and the results showed that for most observers reliable discrimination was achieved at low spatial frequencies.
Journal ArticleDOI
Lateral Interaction between Neural Channels sensitive to Texture Density
TL;DR: The limited retinal range of the interactive process responsible for Mach Bands and the related illusion2 are shown by the gradual disappearance of the illusion as the viewing distance is increased, which can be taken to explain why the middle panel in Fig. 1 is seen as brighter overall than its neighbours.

Application of fourier analysis to the visibility of gratings
F. W. Campbell,John G. Robson +1 more
TL;DR: The contrast thresholds of a variety of grating patterns have been measured over a wide range of spatial frequencies and the results show clear patterns of uniformity in the response to grating noise.

TL;DR: In this paper, it was found that an occipital evoked potential can be elicited in the human by moving a grating pattern without changing the mean light flux entering the eye.
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.

Researches in binocular vision.
TL;DR: This is an original printing in 1950, and the Nathan Library holds a copy of the 1964 reprint (cat No 509) which was published in 1964.

The spatial selectivity of the visual cells of the cat.
TL;DR: Micro‐electrode recordings have been made from single units in the visual cortex of the cat, during stimulation by moving grating patterns generated on a cathode ray tube.
