Seeing Depth

Seeing Depth

1. depth cues: the visual 'clues' that we use to understand depth or distance

2. monocular depth cues: information about distance that comes from one eye

   • these include superimposition, relative size, texture gradient, linear perspective and height in the plane

3. binocular depth cues: information about distance that needs two eyes, such as stereopsis

4. Size Constancy

   • we perceive an object as the same size even when its distance from us changes
   • when an object is close our brain scales it down in size so that it looks normal rather than giant
   • when an object is far away it is scaled up so that it looks like its normal size rather than tiny
