Depth Perception

How do we reconstruct 3D-space from 2D image?

Depth Perception Binocular cues – depend on use of two eyes

retinal disparity images from the two eyes differ closer the object, the larger the disparity Finger sausage example

convergence neuromuscular cue two eyes move inward for near objects

Monocular Cues

Perceptual Organization: Depth Perception

Monocular Cues – depth cues available to either eye alone relative size

smaller image is more distant interposition

closer object blocks distant object relative clarity

hazy object seen as more distant texture coarse --> close

fine --> distant

Perceptual Organization: Depth Perception

Monocular Cues (cont.) relative height

higher objects seen as more distant relative motion

closer objects seem to move faster linear perspective

parallel lines converge with distance relative brightness

closer objects appear brighter
