  ABSTRACT={We present a system for learning descriptions of objects, and for subsequently
     recognizing learned objects, that functions in outdoor, natural environments.
     We describe in detail two modes of functioning within this system: (1) unguided,
     bottom-up learning of object descriptions directly from image data; (2) top-down
     recognition of objects whose approximate position and structure are known by
     use of image-level matching. We then argue that the system’s performance
     in these two modes indicates that robust outdoor performance can be achieved
     within the structure of our vision system.}
