Abstract :
The Night Vision and Electronic Sensors Directorate (NVESD), in conjunction with the project manager for FLIR systems, has committed to the insertion of automatic target recognition algorithms into second generation forward looking infrared (2/sup nd/ Gen FLIR) systems. 2/sup nd/ Gen FLIRs are designed, among other things, to be used by scouts in both offensive and defensive scenarios. Evaluation of the ATR algorithms to be included in 2/sup nd/ Gen FLIR systems has produced a number of significant challenges. Among these are the development of a digital image capture system, development of effective image truth methods, development of scoring concepts for an engineering-level evaluation, and development of scoring concepts appropriate for a user-level evaluation. Both the challenges and the NVESD solutions to these problems are described in detail. Finally, the scout mission is demonstrated and examples of imagery appropriate for the scout problem are reviewed and aspects of human assisted performance results reported.
