Abstract

The present invention provides a document processing device including: a general feature vector memory that stores feature vectors of a shape for each of plural characters; an input unit that optically reads in a document; a extracting unit that extracts feature vectors from the shapes of characters in a document read in by the input unit; a general shape recognition unit that estimates a character for which the feature vectors of its shape extracted by the extracting unit, based on the feature vectors extracted by the extracting unit and the content stored in the general feature vector memory; and a specific feature vector memory that stores the feature vectors extracted by the extracting unit in association with an estimation result of the general shape recognition unit.

Description

Technical field [0001] The present application relates to a technology for improving the recognition accuracy of characters in image data obtained by optically reading a document. Background technique [0002] OCR (Optical Character Recognition), which is a technology for recognizing characters in image data obtained by optically reading a document, is widely used. Various techniques have been proposed in the OCR field to improve the accuracy of character recognition. [0003] It is known to provide a technology for improving the recognition accuracy by updating the recognition dictionary according to the correction operation of the user. Using this technology, characters that cannot be recognized or incorrectly recognized are corrected by a correction operation performed by the user, so that the feature vector of the character shape registered in the feature vector database for correcting the character is updated to be corrected in the recognition The character is the feature ve...
