Claim Text:
1. A method of monitoring the amount of time spent in a specified area by an individual, the method comprising: receiving a plurality of entrance images, each entrance image containing a face of an entering individual that passes a first location; storing each entrance image in a database along with a corresponding entrance time that the entering individual passes the entrance location; receiving an exit image containing a face of an existing individual that passes a second location: storing the exit image along with a corresponding exit time that the exiting individual passes the exit location; comparing the exit image to the entrance images in the database: identifying a matching entrance image containing the same face as the exit image; and determining a stay time for the exiting individual by determining the difference between the entrance time corresponding to the matching entrance image and the exit time; averaging the stay times within the predefined time period to create an average stay time for the predefined time period; and determining stay times of multiple exiting individuals over a predefined time period.
