Natural scenes upset the visual applecart.
The effortless ease of everyday vision seems to contradict numerous findings on the limited capacity of visual attention. However, natural scenes appear to escape the stringent limitations of attention that apply to seemingly far simpler stimuli. This astonishing result will oblige us to rethink the nature of visual attention and its limited capacity.
متن کاملThe use of visual information in natural scenes
Despite the complexity and diversity of natural scenes, humans are very fast and accurate at identifying basic-level scene categories. In this paper we develop a new technique (based on Bubbles, Gosselin & Schyns, 2001a; Schyns, Bonnar, & Gosselin, 2002) to determine some of the information requirements of basic-level scene categorizations. Using 2400 scenes from an established scene database (...
متن کاملVisual perception and the statistical properties of natural scenes.
The environments in which we live and the tasks we must perform to survive and reproduce have shaped the design of our perceptual systems through evolution and experience. Therefore, direct measurement of the statistical regularities in natural environments (scenes) has great potential value for advancing our understanding of visual perception. This review begins with a general discussion of th...
متن کاملSummation of perceptual cues in natural visual scenes
Natural visual scenes are rich in information, and any neural system analysing them must piece together the many messages from large arrays of diverse feature detectors. It is known how threshold detection of compound visual stimuli (sinusoidal gratings) is determined by their components' thresholds. We investigate whether similar combination rules apply to the perception of the complex and sup...
متن کاملVisual search in natural scenes explained by local color properties.
Success in visually searching for a small object or target in a natural scene depends on many factors, including the spatial structure of the scene and the pattern of observers' eye movements. The aim of this study was to determine to what extent local color properties of natural scenes can account for target-detection performance. A computer-controlled high-resolution color monitor was used to...
