Depth Cues
- Monocular Depth
- Binocular depth cues are cues
to distance that need both
eyes. Sometimes two eyes are
important for seeing depth.
- An example of monocular
depth is stereopsis.

- Stereopsis: The greater the difference
between the view seen by the left eye and the
right eye, the closer the viewer is looking.
- The brain can compare the information from left to right
eye. When we are looking at something far away, the two
images look very similar. When out eyes are focused nearer
to us, the views of the left and right eye are more different.

- Superimposition
- Superimposition is when the position of one
object puts it in front of another. It tells us
that the thing you can see must be nearer
than the partially hidden object.

- Relative Size
- Relative size is where objects that make bigger
images on the retina are perceived as being
closer than the ones making smaller images.
- Relative size also indicates depth in photographs and drawings.

- Texture Gradient
- Texture gradient is an area with a
detail pattern is perceived to be
nearer than one with less detail.
- Close up, a textured surface
is very detailed. From
further away, the texture is
less clear.

- Linear Perspective
- Linear perspective is when lines that
are parallel appear to converge in the
distance. The 'lines' themselves do not
have to be actual lines.
- The 'lines' themselves do no t need to be actual lines.

- Height in the Plane
- Height in the plane is where objects
closer to the horizon are perceived
to be more distant than ones
above or below the horizon.
- Height in the plane is where objects
closer to the horizon are perceived
to be more distant than ones
above or below the horizon.
- Monocular depth cues are clues to distance that
only need one eye. If you close one eye and look
around, it is still obvious which things are closer
and which things are further.
