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
