Imagery Exploitation System/Balanced Technology Initiative
Abstract
The Imagery Exploitation System/Balanced Technology Initiative (IES/BTI) 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. IES/BTI 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). IES/BTI employs a coarse-to-fine hierarchical reasoning paradigm, using Bayesian inference for hypotheses management and belief propagation to solve the complex force/terrain/military 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 and/or 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.
