Description Attention focusing mechanisms and domaininformed selection of representations can make realtime vision tasks work with limited computational power. This paper describes ongoing work in distributed real-time vision which aims to use cheap and plentiful workstations and PCs rather than specialpurpose hardware. I discuss a system called Argus which is inspired by the visual routines theory of human vision. In Argus, reactive feature tracking agents maintain minimal, task-dependent descriptions of relevant image features by direct observation of the live video stream. Routines for model-based object recognition operate on these descriptions. Higherlevel processing is independent of the maintenance of lower-level representations. This allows the visual subsystem to provide real-time feedback for closed-loop tasks even when high-level perceptual processing is slow compared to video frame rates. Experiments in moving-object recognition are described which demonstrate the strength of this app...
