Multitarget Tracking Using Optical Processing

Abstract : Our SDIO multitarget tracking optical system is described. It involves point target detection and localization of sub-pixel targets below the noise level (using an optical correlator), track initiation (using an optical Hough transform), data association (using an optical neural net), a simple estimator (alpha, beta, gamma tracker), and inherent error correction (in the full modular system). New algorithms and optical architectures were devised, and real ISTEF data was processed on real-time optical laboratory systems. (Author)
