  • Patent number: 8995741
    Abstract: Embodiments herein provide computer-implemented techniques for allowing a user computing device to extract financial card information using optical character recognition (“OCR”). Extracting financial card information may be improved by applying various classifiers and other transformations to the image data. For example, applying a linear classifier to the image to determine digit locations before applying the OCR algorithm allows the user computing device to use less processing capacity to extract accurate card data. The OCR application may train a classifier to use the wear patterns of a card to improve OCR algorithm performance. The OCR application may apply a linear classifier and then a nonlinear classifier to improve the performance and the accuracy of the OCR algorithm. The OCR application uses the known digit patterns used by typical credit and debit cards to improve the accuracy of the OCR algorithm.

  • Patent number: 8947745
    Abstract: A imaging scanner identifies first and second locations in a first and second captured image of a document, analyzes each character in the identified locations, and produces a first and second string, each including a character and a confidence value. The device determines that a first measurement of the confidence values in each of the first and second string is beyond a range of a first threshold. The device compares the confidence value for each character in the first string with a corresponding confidence value in the second string, selects a character from one of the first or second string with a higher confidence value; and produces a combined string including the selected characters and the confidence value associated with each selected character.

  • Patent number: 8934676
    Abstract: A method and system for achieving accurate segmentation of characters with respect to a license plate image within a tight bounding box image. A vehicle image can be captured by an image capturing unit and processed utilizing an ALPR unit. A vertical projection histogram can be calculated to produce an initial character boundary (cuts) and local statistical information can be employed to split a large cut and insert a missing character. The cut can be classified as a valid and/or a suspect character and the suspect character can be analyzed. The suspect character can be normalized and passed to an OCR module for decoding and generating a confidence quote with every conclusion. The non-character images can be rejected at the OCR level by enforcing a confidence threshold. An adjoining suspect narrow character can be combined and the OCR confidence of the combined character can be assessed.

  • Patent number: 8917936
    Abstract: An image pickup element capture an image of an object, and detailed unique information relating to the captured image is automatically associated with the image through pattern recognition so that the image is easily managed. A pattern detector performs the pattern recognition on an image obtained through a pre-photographing operation, and a result of the recognition is stored in a memory. A code comparator compares stored a preceding recognition result with the latest recognition result obtained through the pattern recognition performed using the pattern detector. In accordance with a result of the comparison, the stored recognition result is updated. When it is determined that a predetermined pattern is not included in the image obtained using the image pickup element, the recognition result stored in the memory is associated with the captured image.

  • Patent number: 8903136
    Abstract: The technology of the present disclosure includes computer-implemented methods, computer program products, and systems to filter images before transmitting to a system for optical character recognition (“OCR”). A user computing device obtains a first image of the card from the digital scan of a physical card and analyzes features of the first image, the analysis being sufficient to determine if the first image is likely to be usable by an OCR algorithm. If the user computing device determines that the first image is likely to be usable, then the first image is transmitted to an OCR system associated with the OCR algorithm. Upon a determination that the first image is unlikely to be usable, a second image of the card from the digital scan of the physical card is analyzed. The optical character recognition system performs an optical character recognition algorithm on the filtered card.

  • Patent number: 8891822
    Abstract: A system and method for script and orientation detection of images using artificial neural networks (ANNs) are disclosed. In one example, textual content in the image is extracted. Further, a vertical component run (VCR) and horizontal component run (HCR) are obtained by vectorizing each connected component in the extracted textual content. Furthermore, a zonal density run (ZDR) is obtained for each connected component in the extracted textual content. In addition, a concatenated vertical document vector (VDV), horizontal document vector (HDV), and zonal density vector (ZDV) is computed by normalizing the obtained VCR, HCR, and ZDR, respectively, for each connected component. Moreover, the script in the image is determined using a script detection ANN module and the concatenated VDV, HDV, and ZDV of the image. Also, the orientation of the image is determined using an orientation detection ANN module and the concatenated VDV, HDV, and ZDV of the image.
