Personal information retrieval using knowledge bases for optical character recognition correction

Marco Bressan, +2 more
Abstract: 
In a system for updating a contacts database (42, 46), a portable imager (12) acquires a digital business card image (10). An image segmenter (16) extracts text image segments from the digital business card image. An optical character recognizer (OCR) (26) generates one or more textual content candidates for each text image segment. A scoring processor (36) scores each textual content candidate based on results of database queries respective to the textual content candidates. A content selector (38) selects a textual content candidate for each text image segment based at least on the assigned scores. An interface (50) is configured to update the contacts list based on the selected textual content candidates.

OCR error correction methods and apparatus utilizing contextual comparison

Edward Francis Scanlon
TL;DR: In this paper, the authors proposed methods of correcting optical character recognition errors occurring during recognition of alphanumeric character strings contained within one or more predetermined types of character fields. But these methods require a document processing system having at least one lexicon of character strings consisting of a list of at least a portion of all of the possible character string values for each of the fields being processed.
