Abstract: Electronic Article Surveillance in which a radio frequency identification (RFID) interrogation signal is transmitted, over a first window of time, into an RFID interrogation zone of the EAS system. A plurality of response signals are detected from a first RFID tag of the EAS system responding to the interrogation signal. Over a second window of time overlapping at least in part with the first window of time, image data is captured within a field of view. The field of view and the RFID interrogation zone overlap to form a zone of interest. Movement of a non-tag object is characterized during the first window of time based on the image data. Whether the first RFID tag is associated with the characterized non-tag object is determined based on a comparison of the detected plurality of response signals and the characterized movement of the non-tag object.

Abstract: An EAS system first transmits a radio frequency identification (RFID) interrogation signal into an RFID interrogation zone of an EAS system. The system then first receives at least one RFID response signal from a first RFID tag of the system responding to the interrogation signal. The system second transmits a non-RFID RF signal into a second zone. The second zone and the RFID interrogation zone overlap to form a zone of interest. The system second receives, from the first RFID tag, an indication that the first RFID tag received the second transmission. The system determines, based on receiving both the RFID response signal from a first RFID tag and the indication that the first RFID tag received the second transmission, that the first RFID tag is in the zone of interest.

Abstract: Techniques for distinguishing objects (e.g., an individual or an individual pushing a shopping cart) are disclosed. An object is detected in images of a scene. A height map is generated from the images, and the object is represented as height values in the height map. Based on height properties associated with another object, it is determined whether the other object is associated with the object. If so determined, the objects are classified separately.
