Publication number: 20180039857Abstract: Comparing extracted card data from a continuous scan comprises an optical character recognition (“OCR”) system for extracted data based on three-dimensional models. The system receives a digital scan of a physical card and obtains a plurality of images of the card from the digital scan of the physical card. The system performs an OCR algorithm on a three-dimensional model based on the images and determines if a confidence level of the results are above a preconfigured level. If the results are below the preconfigured levels, a second three dimensional model is created that includes additional received images. When results are over the preconfigured level, the results are accepted as an accurate extraction.Type: ApplicationFiled: July 20, 2017Publication date: February 8, 2018Inventors: Sanjiv Kumar, Henry Allan Rowley, Xiaohang Wang, Yakov Okshtein, Farhan Shamsi, Alessandro Bissacco

Patent number: 9886641Abstract: Extracting card information comprises a server at an optical character recognition (“OCR”) system that interprets data from a card. The OCR system performs an optical character recognition algorithm an image of a card and performs a data recognition algorithm on a machine-readable code on the image of the card. The OCR system compares a series of extracted alphanumeric characters obtained via the optical character recognition process to data extracted from the machine-readable code via the data recognition process and matches the alphanumeric series of characters to a particular series of characters extracted from the machine-readable code. The OCR system determines if the alphanumeric series and the matching series of characters extracted from the machine-readable code comprise any discrepancies and corrects the alphanumeric series of characters based on the particular series of characters extracted from the machine-readable code upon a determination that a discrepancy exists.Type: GrantFiled: September 15, 2016Date of Patent: February 6, 2018Assignee: GOOGLE LLCInventors: Xiaohang Wang, Justin Scheiner, Glenn Berntson

Publication number: 20180014155Abstract: A geofence management system obtains location data for points of interest. The geofence management system determines, at the option of the user, the location of a user mobile computing device relative to specific points of interest and alerts the user when the user nears the points of interest. The geofence management system, however, determines relationships among the identified points of interest, and associates or “clusters” the points of interest together based on the determined relationships. Rather than establishing separate geofences for multiple points of interest, and then alerting the user each time the user's mobile device enters each geofence boundary, the geofence management system establishes a single geofence boundary for the associated points of interest. When the user's mobile device enters the clustered geofence boundary, the geofence management system notifies the user device to alert the user of the entrance event. The user then receives the clustered, geofence-based alert.Type: ApplicationFiled: September 20, 2017Publication date: January 11, 2018Inventors: Xiaohang Wang, Farhan Shamsi, Yakov Okshtein, David Singleton, Debra Lin Repenning, Lixin Zhang, Marcus Alexander Foster

Patent number: 9679225Abstract: 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.Type: GrantFiled: May 26, 2015Date of Patent: June 13, 2017Assignee: GOOGLE INC.Inventors: Sanjiv Kumar, Henry Allan Rowley, Xiaohang Wang, Jose Jeronimo Moreira Rodrigues
