Monocular Cue

Relative Size- Relative size is how humans are able to see things that are similar in size and shape, and identify the smaller image as the object farther away.

                              

  A real life example of relative size is when you look down a hallway and the people down the hallway look smaller than they actually are.          

    

Relative Clarity- Relative clarity is when humans perceive farther away objects as hazy or not detailed, and perceive closer objects as fine and detailed.

A real life example is when you look across a room and objects far way look hazy, while objects up close apprear fine and detailed. This is of course due to the objects distance from your point of view. Pencil is detailed while hallway outside of room is hazy.
