Depth Perception Flashcards

Depth Perception

• Refers to the visual ability to perceive three-dimensionality and evaluate distances between objects.

Visual Cliff

• A tool used in research to assess depth perception, especially in infants and young animals, by creating an illusion of a drop-off.

Binocular Cues

• Depth cues that necessitate the use of both eyes for effective distance judgment.

Monocular Cues

• Depth cues that can be utilized with just one eye to determine distance and depth.

Retinal Disparity

• A crucial binocular depth cue derived from the slight differences in images that each retina (left and right eye) receives, allowing the brain to compute distance.

Convergence

• Another binocular depth cue, it occurs when eye muscles exert tension as both eyes turn inward to focus on nearby objects, indicating proximity.

Relative Size

• A monocular depth cue where an object's perceived size increases as it approaches and appears smaller as it moves further away, based on known object sizes.

Relative Motion

• A monocular depth cue illustrating that objects in the foreground appear to move faster than those in the background, indicating distance.

Interposition

• Monocular depth cue where an object that partially obscures another is perceived as closer, reinforcing the concept of depth.

Relative Height

• A monocular depth cue suggesting that distant objects appear higher in the visual field than closer ones, aiding in depth perception.

Texture Gradient

• A monocular depth cue where textures appear finer and smoother as they recede into the distance, providing depth information.

Relative Clarity

• Monocular depth cue stating that objects further away appear less distinct or blurry compared to closer objects, aiding in depth perception.

Linear Perspective

• A monocular depth cue where parallel lines seem to converge in the distance, creating an illusion of depth on two-dimensional surfaces.
