  • Systems and methods for triage of passages of text output from an OCR system
    Patent number: 7171061
    Abstract: Systems and methods for triage of passages of text output from an OCR system by use of trainable models of the accuracy of the OCR system based on attributes of individual characters. The systems and methods according to this invention automatically triage an OCR-output text passage by determining at least one OCR-output character attribute for each OCR-output character, determining an error rate for the OCR-output text passage using a triage model and the determined at least one OCR-output character attribute, and comparing the determined error rate for the OCR-output text passage with an OCR-output text passage threshold error rate to perform an OCR-output text passage triage decision. Triage decision includes for example, sending OCR results directly to an end user without any post-OCR processing, sending the OCR results through a post-OCR inspection and processing stage, sending the original document image to be completely keyed in manually, and a combination thereof.

  • SYSTEMS AND METHODS FOR CREATING MULTI-LAYERED OPTICAL CHARACTER RECOGNITION (OCR) DOCUMENTS
    Publication number: 20180217973
    Abstract: The present disclosure discloses methods and systems for creating a multi-layered Optical Character Recognition (OCR) document, the multi-layered OCR document facilitates selection of the desired text from the multi-layered OCR document. The method includes receiving a scanned image corresponding to a document, the document includes text information. A binary image is generated from the scanned image. Then, a morphological dilation operation is performed to create one or more text groups, using a horizontal structuring element and a vertical structuring element. Thereafter, OCR operation is applied on each text group to generate a corresponding OCR layer. The one or more OCR layers are then combined while creating a multi-layered OCR document. Finally, the combined OCR layers are superimposed as invisible text layers over the scanned image to create the multi-layered OCR document.

  • DYNAMIC SERVICE CONFIGURATION DURING OCR CAPTURE
    Publication number: 20150049947
    Abstract: Dynamically configuring OCR processing may include determining a device type and determining whether to perform optical character recognition (OCR) processing of the received image locally based on one or more OCR parameters. Example OCR parameters may include the device type, the image type, the size of the received image, the available amount of the memory, the measured/benchmarked throughput of OCR processing on the device relative to an OCR server throughput and network throughput, and/or the current level of network connectivity. If it is determined that OCR processing of the received image should be performed locally, the device may compute one or more name-value pairs corresponding to the received image and transmit the name-value pairs to a remote data server for processing.

  • AUTOMATIC OPTICAL CHARACTER RECOGNITION (OCR) CORRECTION
    Publication number: 20200380286
    Abstract: Disclosed herein are computer-implemented methods, computer-implemented systems, and non-transitory, computer-readable media for automatic Optical Character Recognition (OCR) correction. One computer-implemented method includes evaluating an OCR result using a trained Long short-term memory (LSTM) neural network language model to determine whether correction to the OCR result is required. If correction to the OCR result is required, a most similar text relative to the OCR result is determined from a name and address corpus using a modified edit distance technique. The OCR result is corrected with the determined most similar text.
