Image structure entails spatial variations of intensity, texture, and motion, jointly structured by observed surfaces. The spatial structure of binocular ... Binocular vision is vision with two eyes, and the main cue for depth perception associated with binocular vision is retinal disparity. Since the pupils of the eyes are roughly about three inches apart, this means that the right eye gives a slightly different image to that of the left eye. The disparity ( difference) between these two retinal ...This test was designed to simplify stereopsis screening in children. The test is a single card that can be held easily by the clinician or the patient. It only assesses gross stereopsis and provides targets of a moon arc (200 seconds), star (200 seconds), car (400 seconds) and an elephant (600 seconds).Depth perception. Seeing with two eyes helps people to judge distances and to see in 3D, but even using one eye, there are many clues (often referred to as visual cues) to give people depth perception. Depth perception using computers is more difficult.In this review, I examine the evidence for impairment of binocular vision and depth perception that can result from insults to the brain, including both discrete damage, temporal lobectomy and more systemic diseases such as posterior cortical atrophy.This article is part of the themed issue 'Vision in our three-dimensional world'.The term depth perception refers to our ability to determine distances between objects and see the world in three dimensions. To do this accurately, one must have binocular stereoscopic vision, or stereopsis. If someone lacks stereopsis, they are forced to rely on other visual cues to gauge depth, and their depth perception will be less ...In humans, monocular vision entails reliance on only one eye, due to circumstances such as injury which result in the other eye being unusable. 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.

The stimuli can only be perceived clearly by using both eyes. In other words, binocular cues are the ability to perceive the world in 3D by using both eyes. Convergence and retinal disparity are the two binocular cues: There are basically 4 categories of depth cues: Static monocular, depth from motion, binocular and physiological cues [2]. We subconsciously take advantage of these signals to perceive depth …The perceived depth of the monocular stimulus also depended on whether it was seen as in front of or behind the binocular stimulus, which might be due to the fact that the stereoscopic depth of ...Binocular Cues. Binocular cues depend on the use of both eyes. The main binocular cue is retinal disparity, the difference between the two retinal images that result due to your eyes being about 2.5 inches apart. Your brain judges distance by comparing these images; the greater the disparity (difference), the closer the image is.
