An experimental target recognition system (XTRS) for detecting and recognizing target vehicles in laser radar imagery is discussed. XTRS is a model-based system with four major processing stages; detection, extraction, decomposition, and matching. Recognition decisions are made by comparing image features and their spatial relationships to a hierarchical library of target appearance models. Laser radar sensors and the imagery they produce are briefly described. XTRS and its processing stages are described. System performance on several data sets is discussed |
