摘要:
An approach that allows for detecting and deterring RFID tag related fraud is provided. In one embodiment, there is a generating tool configured to generate a set of tag-item models based on results of a cumulative training process; detecting tool configured to detect discrepancy between an expected appearance of the item as determined from analyzing corresponding tag-item model and an actual appearance of the item as captured by color camera, and an acknowledging tool configured to acknowledge said detected discrepancy.

The present invention generally provides an exit security approach. Specifically, among other things, under the present invention: an item image for at least one of a set of items at a shopping checkout station is received; a receipt corresponding to the set of items is received; a first receptacle image of a shopping receptacle holding the set of items is received; a second receptacle image of the shopping receptacle is received; an integrity of the receipt is verified; the first receptacle image is compared to the second receptacle image; and it is determined whether a discrepancy exists based on at least one of the verification of the receipt and the comparison of the first receptacle image to the second receptacle image.

Aspects of the present invention provide an approach for deterring checkout fraud comprising a camera (e.g., still, video, etc.) that is located near (overhead) a scanner used to scan a barcode of an item being purchased. Specifically, the barcode of the item is scanned and an image of the item is recorded. It is then determined whether the identity of the item as determined based on the barcode is consistent with its appearance as determined from the image. If not, a discrepancy is registered. It is then determined whether the discrepancy is due to fraud (e.g., theft) or device error. In the case of the latter, the system can be updated to prevent a repeat of the error. In either event, the scan, the image and a shopping event corresponding to the scan and image can be logged for future analysis and/or learning.

The present invention provides an approach for determining a state of a shopping receptacle. Specifically, under the present approach, an image capture device (e.g., camera) is positioned at the checkout station and/or on the shopping receptacle. The device will capture at least one image of the shopping receptacle during the checkout process and/or when the customer or checkout clerk indicates that the transaction is ready for payment (e.g., all items have been scanned or rung through). Using such image(s), a model for an empty receptacle and a knowledgebase of non-shopping items that may remain in the shopping receptacle, it is determined whether the receptacle is empty. If not, an alarm or other notification will be activated and the events can be logged.

The present invention provides an approach for rewarding customers for use of self-checkout stations and, optionally, for being self-sufficient in such use by not requiring retailer (employee) assistance. Specifically, the under the present invention, a set of service choices made by a customer during purchasing transactions are tracked. Such service choices include whether the customer elected to use self-checkout stations. In addition, a frequency of assistance needed by the customer during the purchasing transactions will be tracked. Such tracking can be accomplished using any known technology including the use of the customer loyalty cards that are assigned to specific customers. In any event, a reward can be offered to the customer if the customer elected to use self-checkout stations to complete at least a subset of the purchasing transactions, and/or if the frequency of assistance needed by the customer during the purchasing transactions fell below a predetermined threshold.
摘要:
A novel system and method of treating the output of moving cameras, in particular ones that enable the application of conventional “static camera” algorithms, e.g., to enable the continuous vigilance of computer surveillance technology to be applied to moving cameras that cover a wide area. According to the invention, a single camera is deployed to cover an area that might require many static cameras and a corresponding number of processing units. A novel system for processing the main video sufficiently enables long-term change detection, particularly the observation that a static object has been moved or has appeared, for instance detecting the parking and departure of vehicles in a parking lot, the arrival of trains in stations, delivery of goods, arrival and dispersal of people, or any other application.

A method for detecting a non-scan at a retail checkout station includes detecting the passing of an item across a scanner device of a retail checkout station, obtaining an image of the item passing across the scanner, detecting a scan of an item passing across the scanner to establish a scanned item, and establishing a register associated with the scanned item. A scan occurs if the image of the item passing across the scanner substantially matches the register associated with the scanned item. Conversely, a non-scan is triggered when the image of the item passing across the scanner does not match the register associated with the scanned item.
摘要:
A system, method and program product for providing a video surveillance system that enhances object detection by utilizing feedback from a tracking system to an object detection system. A system is provided that includes: a moving object detection system for detecting moving objects in a video input; an object tracking system for tracking a detected moving object in successive time instants; and a tracker feedback system for feeding tracking information from the object tracking system to the moving object detection system to enhance object detection.

Under the present invention, item verification is automated and expedited. Specifically, items to be purchased can be scanned by the shopper using a barcode reader (e.g., a scanner) attached to or positioned near the shopping receptacle. As items are scanned, they are identified based on their barcode and added to an item list. Item verification can then performed at checkout using imaging technology. For example, the shopping cart or shopping basket can be brought into the field of view of a computer-connected camera. The camera and computer can, working from the customer's item list developed when the items are scanned, observe each product in the receptacle and “ring it up”. If all products can be accounted for, the customer is free to leave; otherwise the customer is denied egress, informed of the problem, etc. A store employee can also be signaled to investigate. The total time required to make the decision is the time to take a picture and process it, which by human standards is very fast; faster than existing verification methods.
摘要:
Events are classified through string pattern recognition. Text labels are assigned to image primitives in a time-ordered set of training images and to related time-ordered transactions in an associated training transaction log in a combined time-ordered training string of text labels as a function of image types. Transactions are labeled in a training transaction log with a transaction label, a training primitive image of a start of a transaction with a start image text label, a training primitive of an entry of a transaction into the log with an entry image text label, and a training primitive of a conclusion of a transaction with an ending image text label. Positive subset string patterns are discovered representing true events from the combined time-ordered training string of text labels, and negative subset string patterns defined by removing single transaction primitive labels from the positive subset string patterns.
