Naturalistic Depth Perception

The Perception and Memory of Stereoscopic Depth Information in Naturalistic Objects

In two experiments with 162 participants, we examined the role of stereoscopic depth cues in the memory for objects and scenes. Stereoscopic depth cues are formed by disparities in the locations of objects in the images formed on the two eyes, and are naturally used by most observers to recover the distances to objects in the world. Using naturalistic pictures, we determined that stereo depth c...

The (In)Effectiveness of Simulated Blur for Depth Perception in Naturalistic Images

We examine depth perception in images of real scenes with naturalistic variation in pictorial depth cues, simulated dioptric blur and binocular disparity. Light field photographs of natural scenes were taken with a Lytro plenoptic camera that simultaneously captures images at up to 12 focal planes. When accommodation at any given plane was simulated, the corresponding defocus blur at other dept...

Depth perception

Depth perception.

Glossary Cue The signal or information in a two-dimensional image that can be used to infer or reconstruct the spatial relations in a three-dimensional scene. Depth Refers to the distance between a viewer and an object as well to the distance between two objects that extend away from a viewer. This is the missing dimension when depicting a three-dimensional scene in a two-dimensional image, whe...

A Naturalistic, Reflexive Dispositional Approach to Perception

This paper will investigate the basic question of the nature of perception, as theoretically approached from a purely naturalistic standpoint. An adequate theory must not only have clear application to a world full of pre-existing biological examples of perception of all kinds, from unicellular perception to conscious human perception, but it must also satisfy a series of theoretical or philoso...
