  • Patent number: 10659456
    Abstract: A device and method for authenticating a user of a wearable biometric device. The method involves performing an initial biometric authentication of the user, the authentication being based on biometric features extracted from one or more image frames corresponding to a first portion of the user's hand and/or wrist, captured with a camera of a wearable device. A second part of the authentication method involves either re-confirming the initial biometric authentication of the user or verifying the liveness of the user or both re-confirming the authentication and verifying the liveness. The second step of the method is based on at least a measure of a second portion of the user's hand or wrist taken when the wearable device is worn against the user's hand or wrist. A notable part of the method is that the initial biometric authentication is performed by temporarily moving the camera away from the first portion of the user's hand and/or wrist.

  • Patent number: 8881986
    Abstract: Various algorithms are presented that enable an image of a machine-readable code, captured by a camera of an electronic device, to be decoded on the device without need to upload the image information to a server for processing. The algorithms can account for variations in focus of the image, as may result in blur due to move movement or auto-focus features. The approaches can handle multiple machine-readable code formats, and can handle machine-readable code on curved surfaces, machine-readable code with damaged areas, or machine-readable code that are otherwise uneven. Such algorithms are highly accurate while being fast and lightweight enough to execute on portable electronic devices, such as tablet computers and smart phones.

  • Patent number: 8851378
    Abstract: In a system and method of recognizing a barcode from a stream of video frames, a processor-implemented camera module receives a stream of video frames, with at least one video frame including a barcode. A processor-implemented barcode blur estimate module estimates an amount of defocus blur in a video frame. The processor-implemented barcode blur estimate module further estimates an identity of the barcode. A processor-implemented barcode localization module identifies a region of the video frame containing the barcode. A processor-implemented barcode geometric modeler module generates a geometric model of the barcode that includes an identified barcode deformity. A processor-implemented barcode decoder module decodes the barcode from the video frame using the estimated amount of defocus blur, the estimated identity of the barcode, and the geometric model of the barcode.
