The Gist of a Scene: Recognizing the Visual World on the Fly
Dr. Aude Oliva
Monday, November 14, 2005, 02:00pm - 03:00pm
MIT, Department of Brain and Cognitive Sciences
Humans can recognize the gist of a scene in a single glance, independent of the complexity of the visual image. How is this remarkable feat accomplished? Research over the last decade has made substantial progress toward understanding the mechanisms underlying human object recognition. However, evidence from behavioral, computational and neuroscience investigations have shown that the perception of real-world scenes may engage distinct cognitive and neural mechanisms from those used in object recognition. In this talk, I will present a series of behavioral experiments dedicated to test the representation and the mechanisms that human observers may use to interpret, within a glance, the visual gist of a scene as well as the implications of scene gist on object detection and the visual exploration of a scene.
