Which of the following is NOT a monocular cue for depth?

A) relative size
B) motion parallax
C) convergence
D) texture gradient

Motion Parallax

A depth cue that involves images of objects at different distances moving across the retina at different rates when the observer is in motion.

Relative Size

A perceptual cue that allows the interpretation of the size of an object in comparison to another, contributing to depth perception.

Texture Gradient

A visual cue that refers to the gradual reduction of detail that occurs in surfaces as they recede from the observer, contributing to the perception of depth.
