Document Summary

General description of a scene = the gist of the scene. E. g. flipping through channels, you are able to deduce the gist of each scene you see even if you are only seeing each clip for a second or less. Research by mary potter (1976) showed that observers could identify scenes even if they were only shown for 250 ms (1/4 of a second) with almost 100% accuracy. Fei-fei (2007) did an experiment showing different scenes for varying amounts of time (from 27 ms to 500 ms). Global image features are holistic and rapidly perceived, and contain information that allow us to perceive a scene"s structure and spatial layout. Characteristics which frequently occur in a certain type of scene are known as regularities in the environment . Observers use regularities in the environment to quickly perceive scenes, but are not necessarily aware of the specific information they are using.
