  • Patent number: 10242285
    Abstract: Techniques for improved binarization and extraction of information from digital image data are disclosed in accordance with various embodiments. The inventive concepts include independently binarizing portions of the image data on the basis of individual features, e.g. per connected component, and using multiple different binarization thresholds to obtain the best possible binarization result for each portion of the image data independently binarized. Determining the quality of each binarization result may be based on attempted recognition and/or extraction of information therefrom. Independently binarized portions may be assembled into a contiguous result. In one embodiment, a method includes: identifying a region of interest within a digital image; generating a plurality of binarized images based on the region of interest using different binarization thresholds; and extracting data from some or all of the plurality of binarized images. Corresponding systems and computer program products are also disclosed.

    Abstract: A system for determining the authenticity of an object including a reference-image acquisition module for acquiring a reference-image. The reference-image acquisition module includes a light-source, an imager including an imaging-sensor, and a database coupled with the imager for storing the reference-image. The light-source directs circumferential-light toward an authentication-region on the object. The circumferential-light is at least one of collimated and telecentric. The circumferential-light impinges on the authentication-region from a plurality of different azimuthal directions and at a predetermined oblique angle relative to the normal of a plane defined by said object. A portion of the circumferential-light is reflected from the authentication-region toward a specular reflection region and another portion is scattered from the authentication-region. The imager is focused on the authentication-region and acquires a reference-image. The reference-image is a focused image of the scattered light.

  • Patent number: 10210384
    Abstract: The present disclosure relates to optical character recognition using captured video. According to one embodiment, using a first image in stream of images depicting a document, the device extracts text data in a portion of the document depicted in the first image and determines a first confidence level regarding an accuracy of the extracted text data. If the first confidence level satisfies a threshold value, the device saves the extracted text data as recognized content of the source document. Otherwise, the device extracts the text data from the portion of the document as depicted in one or more second images in the stream and determines a second confidence level for the text data extracted from each second image until identifying one of the second images where the second confidence level associated with the text data extracted from the identified second image satisfies the threshold value.

  • Patent number: 10192127
    Abstract: Embodiments of the present invention provide a system for dynamically tuning optical character recognition (OCR) processes. The system receives or captures an image of a resource document and uses a general or default OCR process to identify a source of the document and values of multiple data fields in the image of the document. When the system determines that a data field is missing or cannot be extracted, it causes a computing device to display the image of the resource document and requests user input of a coordinate area of the missing data field from an associated specialist. Once the user input is received, the system applies a data field-specific OCR process on the coordinate area of the missing data field to extract the value of the data field. This value of the missing data field can be transmitted to a processing system for further processing.
