Abstract:
1. A system comprising: a processor; a radio frequency-based electronic tracking device, the electronic tracking device coupled to the processor; one or more transmitters, the electronic tracking device configurable to read the one or more transmitters; and one or more video sensing devices, the one or more video sensing devices coupled to the processor, wherein the processor is configurable to associate data from the one or more transmitters and data from the one or more video sensing devices; wherein each of the one or more transmitters is configurable to be associated with a particular individual of a group of individuals; wherein the processor is configurable to cluster data from the one or more transmitters; wherein the processor is configurable to analyze the clustered data to determine a group behavior pattern among the group of individuals; wherein the association between the data from the one or more transmitters and the data from the one or more video sensing devices comprises a dynamic Bayesian network; and wherein the dynamic Bayesian network comprises a complex event level, a first simple event level, and second simple event level, wherein data in the first simple event level and the second simple event level originate from both the electronic tracking device and the video sensor.
