Various embodiments herein each include at least one of systems, methods, software, and devices, such as product scanners e.g., barcode scanners) enabled to detect item substitution fraud during a checkout process at facilities, such as retail outlets. One method embodiment that may be performed in part on a product scanner, includes detecting, on a point-of-sale (POS) terminal, an event occurrence associated with at least one validation process. The method may then receive an image from each of at least one camera of a plurality of cameras of the product scanner. The method further includes processing at least one of the received images according to the at least one validation process to obtain a result and providing the result to the POS terminal.

Item substitution fraud detection

An integrated circuit having a CML driver including a driver biasing network. A first output pad and a second output pad are connected to a voltage pad. A first driver is connected to the first output pad and the voltage pad. A second driver is connected to the second output pad and the voltage pad. A first ESD circuit is connected to the voltage pad, the first output pad, and the first driver. A second ESD circuit is connected to the voltage pad, the second output pad, and the second driver. The first ESD circuit biases the first driver toward a voltage of the voltage pad when an ESD event occurs at the first output pad, and the second ESD circuit biases the second driver toward the voltage of the voltage pad when an ESD event occurs at the second output pad.

Structure and method for dynamic biasing to improve ESD robustness of current mode logic (CML) drivers

A system and computer program product for performing visual surveillance of one or more moving objects include registering one or more images captured by one or more cameras, wherein registering the one or more images comprises region-based registration of the one or more images in two or more adjacent frames, performing motion segmentation of the one or more images to detect one or more moving objects and one or more background regions in the one or more images, and tracking the one or more moving objects to facilitate visual surveillance of the one or more moving objects.

Detection and tracking of moving objects

An optical code scanner is presented that includes image capture technology to read optical codes. The optical code scanner captures an image of an optical code and then generates multiple reduced resolution versions of the image. Multiple techniques are applied to the different images to identify a region of interest, enhance the contrast of the image, perform a non-linear local geometrical distortion correction and minimize the spatial resolution required to read the optical code. The techniques reduce the raw processing power and time required to identify and read an optical code.
