Optical mark recognition (OMR) is the scanning of paper to detect the presence or absence of a mark in a predetermined position. [4] Optical mark recognition has evolved from several other technologies. In the early 19th century and 20th century patents were given for machines that would aid the blind. [2]
The Norden Electronic Vote Tallying System was the first to be deployed, but it required the use of special ink to mark the ballot. The Votronic, from 1965, was the first optical mark vote tabulator able to sense marks made with a graphite pencil. [1] The oldest optical-scan voting systems scan ballots using optical mark recognition scanners ...
Video of the process of scanning and real-time optical character recognition (OCR) with a portable scanner. 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 ...
An optical reader is a device that observes visual information and translates it into digital information, [1] 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.
[citation needed] Compared to CMC-7, some pairs of E-13B characters (notably 2 and 5) can produce relatively similar results when magnetically scanned; however, as a fallback if magnetic reading fails, E-13B also performs well under optical character recognition. [1] The E-13B repertoire can be represented in Unicode (see below).
IBM developed a magnetic read head to handle the new standard, releasing the IBM 1210 MICR reader/sorter in 1959. The development work for this product both with read heads and document handling, helped move optical character recognition forward, with development focusing on reading one or two lines of print from a paper document larger than an ...
For photo scanning, it doesn't get better than this $200 scanner from Amazon. You can scan stacks of photos at a time without having to manually open a scanner or align pictures perfectly.
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
