Depth perception is the ability to see the world in three dimensions and judge the distance of objects. It's essential for daily activities like walking and driving. This perception is achieved through monocular cues, such as texture gradient, interposition, relative size, and linear perspective, which require only one eye. Binocular cues, like convergence and stereopsis, involve both eyes and provide a more accurate sense of depth. These cues are crucial for safe interaction with our environment.

Depth perception is crucial for everyday tasks like walking, driving, and grabbing objects
The brain uses depth cues to process and understand depth perception
Monocular cues are visual signals that provide information about depth and can be perceived with one eye
Texture Gradient
Texture gradient is a monocular cue where objects with a finer texture appear further away
Interposition
Interposition is a monocular cue where one object appears closer because it overlaps and hides part of another object
Relative Size
Relative size is a monocular cue where objects of the same known size appear further away when they appear smaller
Monocular cues are crucial for depth perception in situations where only one eye is available or in two-dimensional representations
Binocular cues involve the use of both eyes and include binocular convergence and stereopsis
Binocular Convergence
Binocular convergence occurs when the eyes rotate inward to focus on a nearby object, providing a cue to its distance
Stereopsis
Stereopsis, or retinal disparity, is a binocular cue where the brain uses the slight difference in images seen by each eye to construct a 3D perception
Binocular cues offer a more refined depth perception in three-dimensional space by utilizing visual information from both eyes
Monocular cues can be perceived with one eye, while binocular cues require both eyes
Monocular cues are often used in two-dimensional contexts, while binocular cues are essential for perceiving depth in three-dimensional space
Binocular cues offer a more detailed perception of depth compared to monocular cues
