Multi-Stage Data Fusion in Security and Defence

Pagination or Media Count:
The fundamental problem of target tracking is to estimate the state of one or more objects that persist over time, based on noisy measurements contained in a vast quantity of mostly spurious measurement data. Target tracking is closely related to a number of basic problems in statistical modelling and information extraction from noisy data. Multi-stage processing provides a wealth of processing options that can be exploited to achieve robust and high-performance surveillance. This manuscript describes a number of multi-stage tracking architectures that the author has recently studied. Additionally, we study the target cardinality problem.
