Abstract: A tracking system includes an interface, a memory, and one or more processors. The interface is configured to receive images acquired by a plurality of video cameras installed in a region. The memory is configured to store calibration data that specifies geometrical positions and orientations of respective Fields-Of-View (FOVs) of the cameras. The one or more processors are configured to, based on the images and the calibration data, distinguish between multiple individuals present in the region, and track geometrical paths taken by the individuals in the region.

Abstract: System and method for loss prevention by: processing a first set of images captured by a first set of cameras and depicting interactions between first persons and products in a store, classifying an interaction as one of taking a product or returning a product; identifying a first product taken by a first person and adding the first product to a virtual shopping cart associated with the first person; reidentifying the first person in a checkout area of the store based on a second set of images captured by a second set of cameras; obtaining a scan list for the first person comprising products scanned for the first person; comparing the virtual shopping cart to the scan list; and generating a notification upon determining a discrepancy between the virtual shopping cart and the scan list.
