This dissertation describes methods and improvements on controlling Pan-tilt-zoom (PTZ) cameras for human tracking.It begins by defining the control of PTZ cameras as a decision problem and formulating the corresponding problem as a Bayesian risk minimization.Further improvements are developed by employing historical information, multiple time-step estimations and online decision making for multiple cameras.Topics covered include multiple-view registration, ground plane modeling by planar homographies, occupancy map computation, fluid simulation, Bayesian risk formulation, variable time-step decision making using Dynamic Programming and comparative evaluation of PTZ human tracking methods.
