Approximate Spatial Layout Processing in Early Vision

Abstract

Imagine yourself running through rough terrain, perhaps fleeing a predator, or perhaps chasing after prey. Your visual system does not have time to scrutinize the countless trees, rocks, and other objects you pass by. What you need most is enough spatial information to avoid obstacles, to orient yourself, to pick a path. In this situation, even a rough sketch of the spatial layout of the environment can provide crucial information.
