Visual scenes are categorized by function.

Visual scenes are categorized by function.

How do we know that a kitchen is a kitchen by looking? Traditional models posit that scene categorization is achieved through recognizing necessary and sufficient features and objects, yet there is little consensus about what these may be. However, scene categories should reflect how we use visual information. Therefore, we test the hypothesis that scene categories reflect functions, or the pos...

Are Textureless Scenes Recoverable?

It is widely accepted that textureless surfaces cannot be recovered using passive sensing techniques. The problem is approached by viewing image formation as a fully threedimensional mapping. It is shown that the lens encodes structural information of the scene within a compact threedimensional space behind it. After analyzing the information content of this space and by using its properties we...

Visual Perception: Objects and Scenes

Visual memory for moving scenes.

In the present study, memory for picture boundaries was measured with scenes that simulated self-motion along the depth axis. The results indicated that boundary extension (a distortion in memory for picture boundaries) occurred with moving scenes in the same manner as that reported previously for static scenes. Furthermore, motion affected memory for the boundaries but this effect of motion wa...

Modeling visual attention on scenes

Research in the computational modelling of the visual attention has mushroomed in recent years. First generation of computational models, called bottom-up models, allows to calculate a saliency map indicating the degree of interest of each area of a picture. These models are purely based on the low-level visual features. However, it is now well known that the visual perception is not a purely b...
