Some systems are capable of reproducing formatted output that closely approximates the original page including images, columns, and other non textual components.HistoryeditEarly optical character recognition may be traced to technologies involving telegraphy and creating reading devices for the blind.In 1. Emanuel Goldberg developed a machine that read characters and converted them into standard telegraph code.Concurrently, Edmund Fournier dAlbe developed the Optophone, a handheld scanner that when moved across a printed page, produced tones that corresponded to specific letters or characters.In the late 1. Emanuel Goldberg developed what he called a Statistical Machine for searching microfilm archives using an optical code recognition system.In 1. 93. 1 he was granted USA Patent number 1,8.The patent was acquired by IBM.With the advent of smart phones and smartglasses, OCR can be used in internet connected mobile device applications that extract text captured using the devices camera.These devices that do not have OCR functionality built into the operating system will typically use an OCR API to extract the text from the image file captured and provided by the device.The OCR API returns the extracted text, along with information about the location of the detected text in the original image back to the device app for further processing such as text to speech or display.Blind and visually impaired userseditIn 1.Ray Kurzweil started the company Kurzweil Computer Products, Inc.OCR, which could recognise text printed in virtually any font Kurzweil is often credited with inventing omni font OCR, but it was in use by companies, including Compu.Scan, in the late 1.Kurzweil decided that the best application of this technology would be to create a reading machine for the blind, which would allow blind people to have a computer read text to them out loud.This device required the invention of two enabling technologies the CCDflatbed scanner and the text to speech synthesiser.On January 1. 3, 1.Kurzweil and the leaders of the National Federation of the Blind.In 1. Kurzweil Computer Products began selling a commercial version of the optical character recognition computer program.Lexis. Nexis was one of the first customers, and bought the program to upload legal paper and news documents onto its nascent online databases.Two years later, Kurzweil sold his company to Xerox, which had an interest in further commercialising paper to computer text conversion.Xerox eventually spun it off as Scansoft, which merged with Nuance Communications.The research group headed by A.G. Ramakrishnan at the Medical intelligence and language engineering lab, Indian Institute of Science, has developed Print.To. Braille tool, an open source GUI frontend8 that can be used by any OCR to convert scanned images of printed books to Braille books.In the 2. 00. 0s, OCR was made available online as a service Web.OCR, in a cloud computing environment, and in mobile applications like real time translation of foreign language signs on a smartphone.Various commercial and open source OCR systems are available for most common writing systems, including Latin, Cyrillic, Arabic, Hebrew, Indic, Bengali Bangla, Devanagari, Tamil, Chinese, Japanese, and Korean characters.ApplicationseditOCR engines have been developed into many kinds of domain specific OCR applications, such as receipt OCR, invoice OCR, check OCR, legal billing document OCR.They can be used for Data entry for business documents, e.Automatic number plate recognition.Automatic insurance documents key information extraction.Extracting business card information into a contact list9More quickly make textual versions of printed documents, e.Project Gutenberg.Make electronic images of printed documents searchable, e.Google Books. Converting handwriting in real time to control a computer pen computingDefeating CAPTCHA anti bot systems, though these are specifically designed to prevent OCR.The purpose can also be to test the robustness of CAPTCHA anti bot systems.Assistive technology for blind and visually impaired users.OCR is generally an offline process, which analyses a static document.Handwriting movement analysis can be used as input to handwriting recognition.Instead of merely using the shapes of glyphs and words, this technique is able to capture motions, such as the order in which segments are drawn, the direction, and the pattern of putting the pen down and lifting it.This additional information can make the end to end process more accurate.This technology is also known as on line character recognition, dynamic character recognition, real time character recognition, and intelligent character recognition.TechniqueseditPre processingeditOCR software often pre processes images to improve the chances of successful recognition.Techniques include 1.De skew If the document was not aligned properly when scanned, it may need to be tilted a few degrees clockwise or counterclockwise in order to make lines of text perfectly horizontal or vertical.Despeckle remove positive and negative spots, smoothing edges.Binarisation Convert an image from color or greyscale to black and white called a binary image because there are two colours.The task of binarisation is performed as a simple way of separating the text or any other desired image component from the background.The task of binarisation itself is necessary since most commercial recognition algorithms work only on binary images since it proves to be simpler to do so.In addition, the effectiveness of the binarisation step influences to a significant extent the quality of the character recognition stage and the careful decisions are made in the choice of the binarisation employed for a given input image type since the quality of the binarisation method employed to obtain the binary result depends on the type of the input image scanned document, scene text image, historical degraded document etc.Line removal Cleans up non glyph boxes and lines.Layout analysis or zoning Identifies columns, paragraphs, captions, etc.Especially important in multi column layouts and tables.Line and word detection Establishes baseline for word and character shapes, separates words if necessary.Script recognition In multilingual documents, the script may change at the level of the words and hence, identification of the script is necessary, before the right OCR can be invoked to handle the specific script.Character isolation or segmentation For per character OCR, multiple characters that are connected due to image artifacts must be separated single characters that are broken into multiple pieces due to artifacts must be connected.Normalise aspect ratio and scale2.
