Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo (for example the text on signs and billboards in a landscape photo) or from subtitle text superimposed on an image (for example: from a television broadcast).[1]


Early versions needed to be trained with images of each character, and worked on one font at a time. Advanced systems capable of producing a high degree of recognition accuracy for most fonts are now common, and with support for a variety of digital image file format inputs.[2] Some systems are capable of reproducing formatted output that closely approximates the original page including images, columns, and other non-textual components.


Early optical character recognition may be traced to technologies involving telegraphy and creating reading devices for the blind.[3] In 1914, Emanuel Goldberg developed a machine that read characters and converted them into standard telegraph code.[4] Concurrently, Edmund Fournier d'Albe developed the Optophone, a handheld scanner that when moved across a printed page, produced tones that corresponded to specific letters or characters.[5]


OCR is generally an "offline" process, which analyses a static document. There are cloud based services which provide an online OCR API service. Handwriting movement analysis can be used as input to handwriting recognition.[14] 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".


Software such as Cuneiform and Tesseract use a two-pass approach to character recognition. The second pass is known as "adaptive recognition" and uses the letter shapes recognized with high confidence on the first pass to recognize better the remaining letters on the second pass. This is advantageous for unusual fonts or low-quality scans where the font is distorted (e.g. blurred or faded).[22]


Modern OCR software include Google Docs OCR, ABBYY FineReader and Transym.[26] Others like OCRopus and Tesseract uses neural networks which are trained to recognize whole lines of text instead of focusing on single characters.


Palm OS used a special set of glyphs, known as "Graffiti" which are similar to printed English characters but simplified or modified for easier recognition on the platform's computationally limited hardware. Users would need to learn how to write these special glyphs.


Crowdsourcing humans to perform the character recognition can quickly process images like computer-driven OCR, but with higher accuracy for recognizing images than that obtained via computers. Practical systems include the Amazon Mechanical Turk and reCAPTCHA. The National Library of Finland has developed an online interface for users to correct OCRed texts in the standardized ALTO format.[32] Crowd sourcing has also been used not to perform character recognition directly but to invite software developers to develop image processing algorithms, for example, through the use of rank-order tournaments.[33]


Accuracy rates can be measured in several ways, and how they are measured can greatly affect the reported accuracy rate. For example, if word context (basically a lexicon of words) is not used to correct software finding non-existent words, a character error rate of 1% (99% accuracy) may result in an error rate of 5% (95% accuracy) or worse if the measurement is based on whether each whole word was recognized with no incorrect letters.[36] Using a large enough dataset is so important in a neural network based handwriting recognition solutions. On the other hand, producing natural datasets is very complicated and time-consuming.[37]


Web-based OCR systems for recognizing hand-printed text on the fly have become well known as commercial products in recent years[when?] (see Tablet PC history). Accuracy rates of 80% to 90% on neat, clean hand-printed characters can be achieved by pen computing software, but that accuracy rate still translates to dozens of errors per page, making the technology useful only in very limited applications.[citation needed]


Recognition of cursive text is an active area of research, with recognition rates even lower than that of hand-printed text. Higher rates of recognition of general cursive script will likely not be possible without the use of contextual or grammatical information. For example, recognizing entire words from a dictionary is easier than trying to parse individual characters from script. Reading the Amount line of a cheque (which is always a written-out number) is an example where using a smaller dictionary can increase recognition rates greatly. The shapes of individual cursive characters themselves simply do not contain enough information to accurately (greater than 98%) recognize all handwritten cursive script.[citation needed]


Pharmaceutical products where the data is not encoded within a barcode, such as LOT or REF codes are scanned by optical character recognition. Where there is a barcode as well as text, Scandit Smart Data Capture software handles both simultaneously.


Readiris 17 is the advanced OCR editing software package that automatically converts text from paper documents or images into fully editable files without having to perform all the tedious retyping work! The optical character recognition (OCR) technology used in Readiris 17 allows very accurate document recognition whilst preserving the original page layout.


Today, OCR software is used for automated data entry, pattern recognition, text-to-speech services, indexing documents for search engines, cognitive computing, text mining, key data and machine translation among various other applications. These tools can convert any scanned documents, PDFs or image types into xml, xlsx or csv files.


Nanonets is an AI-based OCR software that automates data capture for intelligent document processing of invoices, receipts, ID cards and more. Nanonets uses advanced OCR, machine learning image processing, and Deep Learning to extract relevant information from unstructured data. It is fast, accurate, easy to use, allows users to build custom OCR models from scratch and has some neat Zapier integrations. Digitize documents, extract data-fields, and integrate with your everyday apps via APIs in a simple, intuitive interface.


Optical character recognition cannot ensure 100% accuracy. It depends on various factors like the recognition algorithms used, your screen resolution, the font style, the color and size your tested application uses to render text, the color of the background on which the text is rendered, the language of your text, and so on.


Optical character recognition (OCR) is a pattern recognition AI-based technology to identify text inside an image and turn it into an editable digital document. If you ever need to make digital data editable like receipts, invoices, or bank statements, usually in image format, then OCR software can help you.


Mundane tasks such as data validation (checking that data falls within expected parameters) and data cleansing (removing invalid entries) are easy to "teach" to RPA systems. At the same time, RPA assists with data ingestion. Optical character recognition-enabled tools can reliably sort documents into the correct repositories or transfer information from documents to recording software.


ICR: ICR is an abbreviation for Intelligent Character Recognition. It is an electronic process similar to OCR, but is designed for the recognition of handwritten characters and their conversion to electronic characters. Because of the highly variable characteristics of handwriting, ICR accuracy tends to be much lower than what is achieved with OCR


Intelligent document processing (IDP) software is a system that uses artificial intelligence, machine learning, and optical character recognition (OCR), in order to recognize, extract, and analyze data and information from unstructured documents.Compare the best Intelligent Document Processing software currently available using the table below.


The core features of intelligent document processing software include the ability to identify and extract data from structured and unstructured documents. This includes the ability to recognize text patterns in the form of letters, numbers or words in different formats (e.g., PDFs or images). Additionally, the software can detect key phrases within documents which are used as clues for extracting relevant information. This eliminates tedious manual tasks such as manually entering data into a spreadsheet or database.


The cost of intelligent document processing software varies depending on the features you need or want. Generally, basic features may range from free to a few hundred dollars per month, while more sophisticated tools with additional features may cost several thousand dollars per month or more. Additionally, some software packages offer discounts for long-term commitments or larger purchases. There are also a variety of open-source options available at no charge.


Intelligent document processing software can integrate with a variety of different types of software to maximize its effectiveness. For example, it can be integrated with optical character recognition (OCR) software in order to extract text from scanned documents and images, and natural language processing (NLP) software which enables the extraction of important information such as dates, keyword phrases, locations, etc. Additionally, many intelligent document processing solutions are capable of using machine learning algorithms to compare elements in documents and determine patterns or similarities between them. This integration makes it possible for businesses to automate complex tasks associated with document processing such as contract analysis or invoice routing. Furthermore, many intelligent document processing solutions also have the capability to connect to external data sources like customer relationship management (CRM) systems in order to enrich the content being processed with contextual data. Finally, these solutions are often capable of integrating with popular storage solutions like Dropbox or Google Drive so that users can easily retrieve processed documents from anywhere.
