Monocular Depth Cues

Monocular Depth Cues

1. Relative Size

   • smaller objects are perceived as further away than larger ones
   • objects making bigger images on the retina are perceived as being closer than ones making smaller images

2. Texture Gradient

   • an area with a detailed pattern is perceived to be nearer than one will less detail
   • close up a textured surface is very detailed, from further away the texture is less clear

3. Height In The Plane

   • objects closer to the horizon are perceived to be more distant than ones below or above the horizon
   • things lower in the scene are closer, those which are higher up are further away

4. Superimposition

   • a partly hidden object must be further away than the object covering it

5. Linear Perspective

   • parallel lines appear to converge in the distance
   • the point on the horizon where the parallel lines meet is called the 'vanishing point'
