Abstract:

The Imagery Exploitation SystemBalanced Technology Initiative IESBTI is a first phase near-real time image exploitation system to support Army Corp intelligence and electronic warfare IEW situation development, target development and target and target acquisition. IESBTI exploits synthetic aperture radar SAR and infrared IR imagery and annotates the presence and type artillery, armor, etc of military units company size and above. IESBTI employs a coarse-to-fine hierarchical reasoning paradigm, using Bayesian inference for hypotheses management and belief propagation to solve the complex forceterrainmilitary situation image understanding problem. Military forces are modeled at multiple levels of abstraction representing force hierarchy, situation and formation. Evidence gathering actions evaluate the closeness of data supporting the hypotheses to the force models using statistical metrics andor expert system rules. Some rules are complex dynamically adapting a static force model to the local terrain and threat situation. A uniform certainty calculus defines how evidence from the model match is applied to the hypotheses.
