Abstract:
1. A processor-readable medium storing code representing instructions to cause a processor to perform a process, the code comprising code to: detect a first object within a defined area using a sensor; produce a position value of the first object based on an indicator from the sensor, the position value including at least two position coordinates and a corresponding time value; associate the position value of the first object with a queue set when at least a portion of the position value of the first object and at least a portion of a position value of a second object satisfies a queue parameter condition, the position value of the second object including at least two position coordinates and a corresponding time value, the position value of the second object being associated with the queue set, the queue set defining a queue associated with a seed location; identify a third object as a final object; and close the queue set for a period of time when at least one of the queue parameter condition or a seed parameter condition is unsatisfied based on a position value of the final object and each track from a plurality of tracks included in the queue set, the position value of the first object being included in a first track from the plurality of tracks, the position value of the second object being included in a second track from the plurality of tracks.
