Cameras that don't move seem doomed to a boring existence, always watching the same ATM, airport security desk, skyline or traffic intersection. But a camera may learn a surprising amount about its surroundings by comparing many pictures taken at different times. Inspired by time-lapse artists Hiroshi Sugimoto and Jason Salavon, I will describe several tools to understand outdoor scenes as viewed from a single location. In order to test these approaches, we have captured images from nearly 1000 webcams every 30 minutes for more than a year. This database (AMOS: Archive of Many Outdoor Scenes) is available for research and I will highlight some of our early results on patterns of image change that seem to be common to all outdoor cameras.
