History: The OCR-A font was created in 1968 by the American Type Founders and it has been among the first optical character recognition typefaces to meet criteria set by the U.S. Bureau of Standards. The design is so simple that it can be easily read by a machine, but it is slightly more difficult to be read by a human eye. The OCR-A is in conformity with the standard X-3.17-1981 (size I) fixed by the American National Standards Institute (ANSI) in 1981. The same design is also specified by the German DIN 66008 standard.

Standard: font print size is 12 points, print density is 10 cpi.

Capability: our OCR-A recognition engine is size independent and is able to read every font size. The basic recognized characters set is made up by the following digits and symbols:

0 1 2 3 4 5 6 7 8 9 - + "hook" "fork" "chair"

Accuracy: with OCR-A recognition engine, accuracy reaches 100% using good quality scanned images; if quality is low or medium, the error rate will usually be less than 0.5%

Technology: our engine is based on three distinct classifiers that use different methods: artificial neural network, features extraction, statistical matrix matching. An expert system, using fuzzy rules, reconciles all the outputs obtaining the best match.

Speed:speed is linked to cpu speed. Using Pentium processors, time performance are usually included between 50 and 150 CPS .

Input: monochrome or grayscale bitmaps with  200 or more DPI resolution are accepted in input. The best results can be reached using grayscale images because, internally, a binarization algorithm is used.

Output:output is made up by recognized characters as well as confidence levels. Placeholders are used for unrecognized or very suspicious characters.

Platform:all of the Windows 95/98/NT/Millennium/2000/Xp platforms are supported.

Packaging: the engine is packaged in DLL format. The total size is less than 1 Mb. No extra file is required.

Licensing: application development requires a SDK license and application distribution requires payment of royalties.

Demo: a free of charge evaluation package is available upon request .

Prices: SDK and licenses prices are available upon request.

Examples:the following images are ALL automatically readable  with 100% accuracy:
