Abstract
In this research, we aim to ground scene recognition on information other than the identity of component objects. Specifically we seek to understand the structure of color cues that allows the express recognition of scene gists. Using the L*a*b* color space we examined the conditions under which chromatic cues concur with brightness to allow a viewer to recognize scenes at a glance. Using different methods, Experiments 1 and 2 tested the hypothesis that colors do contribute when they are diagnostic (i.e., predictive) of a scene category. Experiment 3 examined the structure of colored cues at different spatial scales that are responsible for the effects of color diagnosticity reported in Experiments 1 and 2. Together, the results suggest that colored blobs at a coarse spatial scale concur with luminance cues to form the relevant spatial layout that mediates express scene recognition. © 2000 Academic Press Key Words: scene; color; diagnostic information; recognition; categorization; spatial scale; L*a*b*; spatial layout. In Potter’s (1975) classical scene-recognition experiment, subjects faced a screen on which slides of real-world scenes appeared in rapid succession (at a rate of 125 ms/slide). Their task was to press a button as soon as they detected, e.g., a beach. Subjects ’ efficiency was very high and this presents a puzzling problem for scene analysis: how can a scene be so rapidly recognized despite its variability, large number of component objects, and multiple sources of interfering factors? Following Marr’s (1982) influential conception, scene recognition has
