METHOD AND SYSTEM FOR OPTICAL CHARACTER RECOGNITION THAT SHORT CIRCUIT PROCESSING FOR NON-CHARACTER CONTAINING CANDIDATE SYMBOL IMAGES

摘要

The current document is directed to methods and systems for identifying Chinese, Japanese, Korean, or similar language symbols that correspond to symbol images in a scanned-document image or other text-containing image. In a first processing phase, each symbol image is associated with a set of candidate graphemes. In a second processing phase, each symbol image is evaluated with respect to the set of candidate graphemes identified for the symbol image during the first phase. As candidate graphemes are processed, the currently described methods and systems monitor progress towards identifying a matching grapheme and, when insufficient progress is observed, terminate processing of the candidate graphemes and identify the symbol image as a non-symbol-containing area of the scanned-document image or other text-containing image.

主权项

1. An optical-symbol-recognition system comprising:
one or more processors; one or more memories; one of more data-storage devices; and computer instructions, stored in one or more of the one or more data-storage devices that, when executed by one or more of the one or more processors, control the optical-symbol-recognition system to process a text-containing scanned image of a document by
identifying probable symbol images in the text-containing scanned image of the document,for each identified probable symbol image, identifying and associating with the probable symbol image, in a first processing phase, an ordered set of candidate graphemes, andfor each identified probable symbol image, in a second processing phase, evaluating candidate graphemes associated with the probable symbol image in the first processing phase while monitoring progress towards identifying a matching candidate grapheme for the probable symbol image and terminating evaluation of candidate graphemes when the progress monitoring determines that the probable symbol image does not contain an image of a symbol.
