[O18]Ocr Optical Character Recognition

by Digital Documents, Llc, Dig

Done correctly, OCR enables users to search for and retrieve individual words contained within a file or page. In addition, when a set of files is indexed, users are able to search for keywords across an entire document library and retrieve each page with exact precision. OCR enables users to execute searches in seconds, searches that once could take several hours or days to complete.

However, this technology did not work well on older or poor quality documents that contained mixed fonts or combinations of texts and graphics. Until now!!

Due to several recent technology advances, it is now possible to obtain six-sigma level character accuracy from these types of document collections.

Although it is important to keep in mind that the quality and condition of the paper documents are still key factors in the successful OCR conversion, dramatically improved results can be obtained by enhancing the quality of the scanned image prior to processing.

Noise removal of borders, speckles and skews are now common on the more advanced document scanners.

Furthermore, advanced color filter technologies may be used to reduce any page background colors, in conjunction with multi-light image capture technologies to remove any shadows cast by page creases that could impact image quality or recognition accuracy.

Once document scanning and processing are complete, an OCR text layer can actually be added and hidden behind each image. An additional orientation filter can be used to ensure that the best image is presented to the OCR engines.

To achieve the highest conversion accuracy possible, the characters in the image can be processed using multi-engine OCR voting technologies that rank each character to determine the best text recognition fit. Then once a word is generated, it will be filtered through a proprietary lexicon to ensure the highest quality results.

Finally, this text can be processed utilizing sophisticated layout retention technologies to represent the image text layout, to provide the best possible text representation for precise search and retrieval. After all, isn't that why they call it Optical Character Recognition?
