Abstract : This paper reviews the current status of an ongoing program to demonstrate the application of DARPA Image Understanding research to a photo interpretation system using real imagery. The vision system developed thus far is based on the Acronym vision system, developed by Rod Brooks and Tom Binford at Stanford University on the DARPA Image Understanding Project. This system has provided the basis for a sophisticated vision capability, implemented on a general purpose computer. In particular, the system includes symbolic prediction of shapes from both oblique and vertical camera views, prediction of shadow shapes, a model-driven shape extraction system, area of interest operator, and a situation assessment module to perform temporal analysis. Having recently completed and exercised the first system implementation, this discussion will include both details of system design and issues include both details of system design and issues related to performance and future extension.
