An occlusion is the visual perception of one object being behind or in front of another object, providing information about the order of the layers of texture. [6] The illusion of occlusion is apparent in the effect of illusory contours, where occlusion is perceived despite being non-existent.
Perspective, relative size, occultation and texture gradients all contribute to the three-dimensional appearance of this photo. Depth perception is the ability to perceive distance to objects in the world using the visual system and visual perception.
Occlusion (dentistry), the manner in which the upper and lower teeth come together when the mouth is closed; Occlusion miliaria, a skin condition; Occlusive dressing, an air- and water-tight trauma dressing used in first aid; Vascular occlusion, blockage of a blood vessel
Stability or resistance to visual noise: Because the geons are simple, they are readily supported by the Gestalt property of smooth continuation, rendering their identification robust to partial occlusion and degradation by visual noise as, for example, when a cylinder might be viewed behind a bush.
Individuals have been found to integrate the various stimuli, for example stereoscopic cues and motion occlusion, in different ways. [ 18 ] How the brain combines the different cues – including stereo, motion, vergence angle and monocular cues – for sensing motion in depth and 3D object position is an area of active research in vision ...
Monocular vision [[Visual perception|is known as seeing and using only one eye in the human species. Depth perception in monocular vision is reduced compared to binocular vision, but still is active primarily due to accommodation of the eye and motion parallax.
In experimental psychology, the tunnel effect is the perception as a single object moving beyond an occluding object and then reappearing after a suitable amount of time on the other side of it. This phenomenon has been studied by Burke (1952), who discovered that the optimal amount of time for giving the impression of a single object is ...
Active occlusion algorithms are needed to help people with severe hearing loss adequately. If a person suffers from "near-normal low-frequency hearing and mild to moderate hearing loss of up to 70 dB at mid and high frequencies," hearing aids with increased vent size or hollow ear-molds/domes are more suitable for them in lessening the extent ...
