Optical character recognition. 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 ...
This comparison of optical character recognition software includes: OCR engines, that do the actual character identification. Layout analysis software, that divide scanned documents into zones suitable for OCR. Graphical interfaces to one or more OCR engines. Software development kits that are used to add OCR capabilities to other software (e.g ...
IBM 1287 Optical Reader. The IBM 1287 is an online reader that can optically scan printed paper tapes and cut form documents to generate input data for an IBM System/360 or System/370 host. It can read machine printed data as well as handprinted numbers and optical marks (based on installed model and features).
An optical reader is a device that observes visual information and translates it into digital information, as found within most image and barcode and matrix-code scanners. An example of optical readers are marksense systems for elections where voters mark their choice by filling a rectangle, circle, or oval, or by completing an arrow.
ICR. Intelligent character recognition (ICR) makes use of continuously improving algorithms to collect more information about the variances in hand-printed characters and more precisely identify them. ICR, which was created in the early 1990s to aid in the automation of forms processing, enables the conversion of manually entered data into text ...
Multiline optical-character reader. A multiline optical-character reader, or MLOCR, is a type of mail sorting machine that uses optical character recognition (OCR) technology to determine how to route mail through the postal system. MLOCRs work by capturing images of the front of letter-sized mailpieces, and extracting the entire address from ...
Tesseract is an optical character recognition engine for various operating systems. [5] It is free software, released under the Apache License. [1] [6] [7] Originally developed by Hewlett-Packard as proprietary software in the 1980s, it was released as open source in 2005 and development was sponsored by Google in 2006. [8]
Summary. 1870–1931. Earliest ideas of optical character recognition (OCR) are conceived. Fournier d'Albe's Optophone and Tauschek's Reading Machine are developed as devices to help the blind read. [1] 1931–1954. First OCR tools are invented and applied in industry, able to interpret Morse code and read text out loud.
