1. A system comprising:
- a video surveillance subsystem comprising a plurality of cameras each having a field of view, each field of view comprising a plurality of sub-regions;
a radio-frequency identification subsystem comprising a plurality of radio-frequency stations, each radio-frequency station configured to detect radio-frequency identification tags within a respective operational radius; and
an association module in communication with the video surveillance subsystem and the radio-frequency identification subsystem, the association module for inferring associations among one or more of the sub-regions and one or more of the operational radii, wherein inferring the associations comprises;
determining a first probability that a first one of the sub-regions is associated with a first one of the operational radii based on a detection of a tracked object in both the first sub-region and the first operational radius at a first time; and
determining a second, higher probability that the first sub-region and the first operational radius are associated based on a detection of a tracked object in both the first sub-region and the first operational radius at a second, later time.

11. A method comprising:
-
receiving data from a video surveillance subsystem comprising a plurality of cameras each having a field of view, each field of view comprising a plurality of sub-regions; receiving data from a radio-frequency identification subsystem comprising a plurality of radio-frequency stations, each radio-frequency station configured to detect radio-frequency identification tags within a respective operational radius; and inferring associations among one or more of the sub-regions and one or more of the operational radii based on the data received from the video surveillance system and the data received from the radio-frequency identification subsystem, wherein inferring the associations comprises; determining a first probability that a first one of the sub-regions is associated with a first one of the operational radii based on a detection of a tracked object in both the first sub-region and the first operational radius at a first time; and determining a second, higher probability that the first sub-region and the first operational radius are associated based on a detection of a tracked object in both the first sub-region and the first operational radius at a second, later time. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
