The present disclosure relates to a supplementary device for attachment to an injection device including an imaging arrangement configured to capture an image of a moveable number sleeve of the injection device, a plurality of light sources, and a processor arrangement configured to control operation of the imaging arrangement and the plurality of light sources and to receive image data from the imaging arrangement. In some instances, the processor arrangement is configured to activate the plurality of light sources sequentially and to combine multiple images captured by the imaging apparatus under different illumination conditions into a single image.

A system is described that uses freckles contained within printed content on Federal Reserve Notes (FRN), and the image-capture of such freckles, along with the printed Federal-Reserve-Note Serial Number (FSN) on each FRN, to detect and deter counterfeiting within physical currency systems of the U.S. and countries worldwide. Additionally, databases on Central Monitoring Agency servers (CMA servers) maintain a status on such captured data for FRNs in use, or potential use, by the U.S. Treasury or other currency issuing and oversight agency that maintains CMA servers. Devices that count and scan FRNs, at diverse point-of-sale and other currency-exchange and transaction locations (Transaction Locations), as well as those part of back-office operations at Transaction Locations, capture FRNs and freckle-related content from FRNs, for transmission to CMA servers via the Internet (Internet of Things Architecture or IOTA). The system enables Big Data analytical methods to detect and dramatically reduce or eliminate the use of counterfeited FRNs.

A device is provided that includes a light-sensing layer including photodetectors, a light guide arranged to direct light beams towards a document area, and an angle-selective layer arranged to filter light beams reflected from the document area based on respective angles of incidence of the reflected light beams. The device also includes a controller configured to: operate the light guide to emit light, such that a plurality of light beams is directed towards the document area, where a portion of the light beams is reflected off of the document area and filtered by the angle-selective layer to direct a subset of the reflected light beams to the light-sensing layer. The controller is also configured to receive data indicative of the subset of light beams, generate an image of a document in the document area, detect text in the image, translate the text, and display the translated text on a display.

The present disclosure relates to image processing and analysis and in particular automatic segmentation of identifiable items in an image, for example the segmentation and identification of characters or symbols in an image. Upon user indication, multiple images of a subject are captured and variations between the images are created using lighting, spectral content, angles and other factors. The images are processed together so that characters and symbols may be recognized from the surface of the image subject.

Systems and methods here may be used for capturing images of sample gemstones under structured, filtered illumination for later comparison and image matching for authentication using networked computer systems.
