depth perception

Non-pictorial depth cues

the ones that are NOT the classic pictorial ones (like occlusion, linear perspective, relative size, etc.)

Accommodation

A depth cue that is based on the focusing of the crystalline lens. Lets us focus on things that are near/far.

Vergence

A depth cue when depth is estimated from the convergence (pointing inward) or divergence (pointed outward) of the two eyes

Stereopsis

This is when the brain uses binocular disparity to gauge depth.

Stereopsis

Which cue is the most precise (it’s added in 3D movies)

Accommodation and Vergence

Which depth cues are based on oculomotor cues?

Depth Perception

The ability to estimate the distances (‘depth’) of surfaces

Occlusion

Whatever is doing the ‘covering’ is nearer, whatever is being covered is farther

Linear perspective/ Texture Gradient

More convergence and/or denser texture means farther

Aerial Perspective

Hazier / lower contrast / “bluer” means farther (clearer/sharper means nearer)

Familiar size

Bigger means nearer, smaller means farther

Relative Size

Bigger means nearer (smaller, farther); higher means farther (lower, nearer)

Binocular disparity

the difference in the image each eye receives due to the horizontal separation of the eyes

3D Perception

Which comes first: object recognition or 3D perception?
