Cameras are not used to identify individuals; instead they generate a robust and characteristic visual signature, and probabilistic techniques derived from air and naval theatre tracking are used to construct maximum likelihood tracks. A novel feature of the system is that the topology of the camera network is deduced from very noisy data, and the system performs deductively without an explicit a priori representation of the camera network. Detailed simulation confirms the theoretical analysis and shows the algorithms can perform well. Applications are likely to include reconstructive analysis of criminal acts in public places, route analysis in commercial zones, and security in transport termini.
