Abstract
The perception of a three-dimensional scene involves the perception of the overall depth within the scene, the perception of the layout of objects in the scene, and the perception of characteristics of objects, such as shape and size. The information used in these perceptions may be viewer-centered, based on distances between the eye and points in the scene, or object-centered, based on relative distances among points in the scene. How all of this information is put together is the main focus of our research. Our most recent studies have been concerned with the role of the ground surface in the integration of three-dimensional scenes. We have examined the influence on perceived layout of where an object appears to contact the ground, relative to where it appears to contact other surfaces. We have studied the interaction of ground contact information with several other sources of information for layout, including motion parallax, occlusion and shadow. We use psychophysical methods in which observers judge the relative distances and shapes of objects in real or simulated scenes. In some studies we insert simulated objects into movies of real scenes. The primary purpose of this research is to better understand human perception of the visual world, but it also has implications for AI vision and human factors applications, such as automated highway systems and flight simulators.
