Quantitative depth perception of surfaces with multiple matches

Depth perception of illusory surfaces

The perception of an illusory surface, a subjectively perceived surface that is not given in the image, is one of the most intriguing phenomena in vision. It strongly influences the perception of some fundamental properties, namely, depth, lightness and contours. Recently, we suggested (1) that the context-sensitive mechanism of depth computation plays a key role in creating the illusion, (2) t...

Precision Enhancement of 3D Surfaces from Multiple Compressed Depth Maps

In texture-plus-depth representation of a 3D scene, depth maps from different camera viewpoints are typically lossily compressed via the classical transform coding / coefficient quantization paradigm. In this paper we propose to reduce distortion of the decoded depth maps due to quantization. The key observation is that depth maps from different viewpoints constitute multiple descriptions (MD) ...

Perspective corrected view on (touch-)table surfaces Depth perception on flat surfaces using head tracking

Adding an illusion of depth to touch table surfaces may improve the way users interact with them. Using head tracking and perspective correction an illusion of depth can be created, which may allow more intuitive interaction where the user can use both touch and head movement to use the system. Currently, various solutions for touch tables exist and head tracking systems can be made relatively ...

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...
