Document Summary
Perceiving depth: we need to be able to explain how we get from the at image on the retina to the 3d perception of the scene. Cue approach to depth perception: identifying information in the retinal image that"s correlated with depth in the scene. Ex: when one object partially covers another object; the object that"s partially covered must be farther than the object that"s covering it. Monocular cues: monocular cues work with only 1 eye, include accommodation, pictorial cues, and movement-based cues. Pictorial cues: sources of depth information in a 2d picture. Movement-based cues: sources of depth information created by movement. Relative height: objects with their bases closer to the horizon are usually seen as being more distant. Being higher in the eld of view causes objects on the ground to appear farther away, whereas being lower in the eld of view causes objects in the sky to appear farther away.
