Accurate physics-based sensor simulation for IR, radar, and night vision requires pixel-level classification of materials in terrain imagery and identification of major man-made features in the simulation database. TSC’s Automatic Feature Extractor (AFE) provides this capability in a user-friendly set of tools that interfaces with standard Government simulation databases such as the Common Database (CDB). The tools include an expert system-based classifier that can handle any combination of input imagery, including grayscale, color, and multispectral data. For identifying features, there are tools for extracting buildings, road networks, and waterway networks. The AFE tools are currently available either as stand-alone applications or as plug-ins for ERDAS IMAGINE®.
