Claim 17:
18. A system comprising:
a first camera comprising a first optical sensor having a first field of view and a first processor unit in communication with the first optical sensor;
a second camera comprising a second optical sensor having a second field of view and a second processor unit in communication with the second optical sensor;
a storage unit, wherein at least a portion of the storage unit is within the first field of view and the second field of view;
a sensor associated with the storage unit; and
a server in communication with at least the first camera, the second camera and the sensor,
wherein the server is programmed with one or more sets of instructions that, when executed by the server, cause the server to at least:
determine, by at least one signal received from the sensor, that an event has occurred at a location;
identify a first regression vector from a first portion of a first image captured by the first camera depicting a first head to a second portion of the first image corresponding to the location of the event based at least in part on a first record received from the first camera, wherein the first record is generated by at least the first processor unit;
identify a second regression vector from a third portion of the first image depicting a second head to the second portion of the first image corresponding to the location of the event based at least in part on the first record;
identify a third regression vector from a first portion of a second image captured by the second camera depicting the first head to a second portion of the second image corresponding to the location of the event based at least in part on a second record received from the second camera, wherein the first record is generated by at least the first processor unit;
identify a fourth regression vector from a third portion of the second image depicting the second head to the second portion of the second image corresponding to the location of the event based at least in part on the second record;
calculate a first factor for the first camera based at least in part on a first confidence score in the first regression vector and a second confidence score in the second regression vector;
calculate a second factor for the second camera based at least in part on a third confidence score in the third regression vector and a fourth confidence score in the fourth regression vector;
determine that the location of the event is occluded in the second field of view based at least in part on the second factor; and
in response to determining that the location of the event is occluded in the second field of view,
calculate a fifth confidence score in the first actor based at least in part on the first regression vector;
calculate a sixth confidence score in the second actor based at least in part on the second regression vector; and
determine that the event is associated with one of the first actor or the second actor based at least in part on the fifth confidence score and the sixth confidence score.
