The second set of numbers printed on the bottom of the check represents the bank account number of the associated checking account. Widely used as a form of information entry from printed paper data records — whether passport documents, invoices, , computerised receipts, business cards, mail, printouts of static-data, or any suitable documentation — it is a common method of digitising printed texts so that they can be electronically edited, searched, stored more compactly, displayed on-line, and used in machine processes such as , , extracted , key data and. After processing huge number of such probabilistic hypotheses, the program finally takes the decision, presenting you the recognized text. The image of the page is usually scanned into an image.

Some of these characters are mapped from fonts specific to , or. Paper tape was used as early as 1857 as an input device for telegraph. And the principle of adaptability means that the program must be capable of self-learning. The shapes of individual cursive characters themselves simply do not contain enough information to accurately greater than 98% recognise all handwritten cursive script. Archived from on June 14, 2010. 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.

Knowledge of the grammar of the language being scanned can also help determine if a word is likely to be a verb or a noun, for example, allowing greater accuracy. Crowdsourcing 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. Punch cards were created in 1890 and were used as input devices for computers. Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences. 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.

There is also the possibility of missing data in the scanning process, and incorrectly or unnumbered pages can lead to their being scanned in the wrong order. Also, unless safeguards are in place, a page could be rescanned, providing duplicate data and skewing the data.
