The Benefits Of Optical Character Recognition Software

Although OCR software represents various advantages to any user, they are both particularly beneficial tools for businesses! Indeed, the latter generate large volumes of documents, such as legal contracts, administrative forms, packing slips, licenses, certificates, etc., and OCRs will facilitate their management.

First, the software makes it possible to make a digital archiving of all the elements that the company must keep. In particular, this will make it possible to replace the storage of papers through the random access memories of computers, in order to save space.

Then it will be much easier to make document comparisons to check for possible contradictions of information in the systems. These include, for example, checking the amount of checks, invoices, etc.

Regarding accessibility, digitization is much more practical because once the documents are digitized on a common company database, they become instantly accessible to several users.

Changes, as mentioned above, will also be easier to make! For example, you can update an old contract or modify an old will without spending hours to retype the texts in full. With the help of your OCR, you can easily use any word-processing tool to make the changes.

Additionally, you can save a scanned document as a file. doc, .txt, pdf, etc., and research in a database will be facilitated compared to paper archiving.

Methods Of Operation Of Optical Character Recognition

The difficulty in recognizing different fonts is the main challenge of OCR. Indeed, there are many ways to write symbols, and the image to be reworked must be preprocessed in order to ensure the reading of the text. The varieties of OCR softwares notably use the same operating principles.


This first step allows OCR software to increase the chances of handwriting recognition.

It mainly includes

  • Realignment: the body of the text must be perfectly aligned horizontally and vertically before processing. It can thus be turned a few degrees (clockwise or anti-clockwise) in order to ensure the accuracy of the reading.

  • Deworming: this consists of removing unnecessary tasks from the document to be processed.

  • Binarization: it is a fact of converting the image into only two colors, black and white. This task is the easiest and most accurate way to distinguish background texts.

  • Deleting unnecessary lines.

  • Layout analysis: this involves identifying paragraphs, captions, and columns. This analysis is particularly important for multicolumn tables for example.

  • Word detection: it allows you to work on basic characters and words, by establishing shapes.

  • Recognition of the script: the script of a text can be transformed at the level of the words when one is in the presence of several linguistic documents. It is, therefore, essential to carry out its identification in this pre-processing phase.

Extracting Statistical Properties From Images

Two main methods can be used to do image extraction in OCR. It is:

  • The detection algorithm makes it possible to define a character, thanks to the evaluation of strokes and lines.

  • Pattern recognition identifies the whole character.

A line of text is recognizable by the lines of white pixels, which provide black pixels in between. With the same method, it is possible to recognize the beginning and the end of a character.


consists of providing clarifications and improvements to OCR when the tool is limited by a lexicon. For example, the lexicon could detect and understand words in English, and it would also be effective in deciphering technical or specific words relating to a particular field. However, the method may be less efficient when the lexicon does not include all the moments of the document that you need to work on (such as the case of proper names, etc.). Nevertheless, several OCR libraries exist on the internet, and they are free.

The Sectors Where Optical Character Recognition Is Used The Most

The Banking Sector:

Banks are among the largest users of OCR software, due to the management of checks. Indeed, the handwritten check can be digitized, and its details can therefore be transformed into digital text. There will only be the validation of the signature, and the check can be approved in real-time. This fast processing is beneficial for the bank, the debtor, and the creditor.

Legal Affairs:

The legal industry generates the most paperwork, so the need for OCR tools in this sector is obvious. With optical character designation recognition, digitization and storage in a database are now possible for printed documents, and accessibility to searches will be much easier. These may be judgments, opinions, wills, documents, etc.


The digitization of medical records with OCR is also very practical for archiving and monitoring patient records. These may include medical prescriptions, x-rays, health reports, insurance, etc.
