Client side filtering of card OCR images

摘要

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.

主权项

1. A computer-implemented method to filter images before transmission to optical character recognition systems to reduce unnecessary communications and processing of unusable images, comprising:
capturing, by a mobile computing device, a first image of a card; analyzing, by the mobile computing device, features of the first image to determine whether the first image is likely to be usable by an optical character recognition algorithm operating on an optical character recognition system; capturing, by the mobile computing device, a second image of the card in response to determining that the first image is not likely to be usable by an optical character recognition algorithm operating on an optical character recognition system; analyzing, by the mobile computing device, features of the second image to determine whether the second image is likely to be usable by an optical character recognition algorithm operating on the optical character recognition system; transmitting, by the mobile computing device, the second image to the optical character recognition system associated with the optical character recognition algorithm in response to determining that the second image is likely to be usable by the optical character recognition algorithm; performing, by the optical character recognition system, the optical character recognition algorithm on the second image to extract relevant data; and receiving, by the mobile computing device and from the optical character recognition system, the relevant data.
