Abstract: A transaction monitoring system is provided for monitoring transactions in a variety of transaction locations such a retail locations or gambling or other locations. The transaction monitoring system uses a multi-modal sensor an comprises a system controller that uses multi-modal sensor data to detect abnormal activity. The transaction monitoring system may capture and/or use image data and depth data. The transaction monitoring system may be used to detect theft or fraud for example by determining when there is an unscanned item, an occluded item, an incorrectly scanned item, unmatched plurality or incorrect capital exchange. To this end, the transaction monitoring system may also receive transaction input such as barcode data, or capital exchange data. Also provided is a transaction monitoring method and a system controller for a transaction monitoring system.

Abstract: A method to detect video copying based on content. The method comprises providing a set of reference data elements derived from a set of reference video frames in a reference video stream; providing a set of query data elements derived from a set of query video frames in a query video stream, each of the query data elements having a corresponding query data element identifier; associating with each of the reference data elements a fingerprint selected from among the query data element identifiers; and determining a similarity measure for the query video stream relative to the reference video stream by a comparison of the query data element identifiers to the fingerprints.
