Convergence is a binocular oculomotor cue for distance and depth perception. Because of stereopsis, the two eyeballs focus on the same object; in doing so they converge. The convergence will stretch the extraocular muscles – the receptors for this are muscle spindles .
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 dorsal pathway generally performs a cross-correlation based upon the region of the different retinal images, while the ventral pathway fixes the multiple ...
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]
Principle of binocular vision with horopter shown. In biology, binocular vision is a type of vision in which an animal has two eyes capable of facing the same direction to perceive a single three-dimensional image of its surroundings. Binocular vision does not typically refer to vision where an animal has eyes on opposite sides of its head and ...
Binocular disparity refers to the difference in image location of an object seen by the left and right eyes, resulting from the eyes' horizontal separation . The mind uses binocular disparity to extract depth information from the two-dimensional retinal images in stereopsis .
A cue is some organization of the data present in the signal which allows for meaningful extrapolation. For example, sensory cues include visual cues, auditory cues, haptic cues, olfactory cues and environmental cues. Sensory cues are a fundamental part of theories of perception, especially theories of appearance (how things look).
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.
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
