Depth sensation is the corresponding term for non-human animals, since although it is known that they can sense the distance of an object, it is not known whether they perceive it in the same way that humans do. [1] Depth perception arises from a variety of depth cues. These are typically classified into binocular cues and monocular cues ...
Certain cues help establish depth perception. Binocular cues are made by humans' two eyes, which are subconsciously compared to calculate distance. [16] This idea of two separate images is used by 3-D and VR filmmakers to give two dimensional footage the element of depth. Monocular cues can be
Cats, like rats, are nocturnal animals, sensitive to tactual cues from their vibrissae. But the cat, as a predator, must rely more on its sight. Kittens were observed to have excellent depth-discrimination. At four weeks, the earliest age that a kitten can skillfully move about, they preferred the shallow side of the cliff.
Binocular neurons create depth perception through computation of relative and absolute disparity created by differences in the distance between the left and right eyes. Binocular neurons in the dorsal and ventral pathways combine to create depth perception, however, the two pathways perform differ in the type of stereo computation they perform. [7]
The coarse stereoscopic system seems to be able to provide residual binocular depth information in some individuals who lack fine stereopsis. [17] Individuals have been found to integrate the various stimuli, for example stereoscopic cues and motion occlusion, in different ways. [18]
In order for stereopsis to occur, an individual must be able to make use of binocular depth cues, a skill the namesake of the term would not be able to utilize. Binocular disparity as it relates to cyclopean images has become an interest in research [7] due to a rise in three dimensional technology usage.
The depth level of each point in the combined image can be represented by a grayscale pixel on a 2D image, for the benefit of the reader. The closer a point appears to the brain, the brighter it is painted. Thus, the way the brain perceives depth using binocular vision can be captured by a depth map (Cyclopean image) painted based on coordinate ...
How the brain combines different cues, including stereo cues, motion cues (both temporal changes in disparity and monocular velocity ratios [8]), vergence angle and monocular cues for sensing motion in depth and 3D object position is an area of active research in vision science and neighboring disciplines.
