Depth Perception

Depth perception

Depth perception.

Glossary Cue The signal or information in a two-dimensional image that can be used to infer or reconstruct the spatial relations in a three-dimensional scene. Depth Refers to the distance between a viewer and an object as well to the distance between two objects that extend away from a viewer. This is the missing dimension when depicting a three-dimensional scene in a two-dimensional image, whe...

Depth perception in strabismus.

Depth perception in strabismus SIR, Recently Henson and Williams published an article entitled 'Depth perception in strabismus." Regettably, the authors did not review the literature completely. If they had, they would have noted that Cooper and Warshowsky2 scientifically evaluated monocular cues in the Titmus stereo test, and that Cooper and Feldman36 looked at the availability of monocular cu...

Human Depth Perception

we introduce the perceptual issues relevant to seeing three dimensions in digital imagery. Technological constraints like limited field-of-view and spatial resolution prevent the display of images that match the real world in all respects. Therefore, only some elements of real world depth perception are utilized when viewing 3D CGI. Depth Cue Theory is the main theory of depth perception. It st...

Depth perception in strabismus.

The monocular and binocular depth thresholds of strabismic subjects have been measured with a modified Howard-Dolman apparatus. Seven out of the 14 strabismic subjects tested were found to have binocular thresholds significantly higher than their monocular ones. These strabismic subjects all had small angles of deviation less than 8 prism dioptres and high acuities in both eyes.
