What is OCR?

OCR stands for Optical Character Recognition. It stands for the process of converting printed material into word alter files or text files that can be read, edited, and managed using computers. OCR also refers to the automated or electronic conversion of written words to typewritten data into this form. Typically, OCR software is used to carry out this growth.

Why do we Need OCR?

To have a pc, tablet, smartphone, or other gadgets ‘read’ data that is not in computer-compatible forms, such as words on a printed page, it has to be examined and maintain into a scanner or sent digitally using email. However, this data is reserved as an ‘image’ as far as the computer is concerned, not text. That means none of the responses that you can implement on text (editing, formatting, deleting, etc.) can be carried out on this ‘image.’ OCR turns this ‘image’ into text so that it is in a more practical, usable form. In effect, OCR can convert graphic images from a scanner (from, say, a JPG or PDF file) into a TXT or DOC file that can be processed easily.

How Does OCR Work?

By increasing this to apply in writing notes, we can see that using OCR technology does much more than simply recognize and convert patterns into text. No two people write the same way, which means that OCR on writing recognition software encounters different patterns that may denote the same letter or word. Books, reports, and pages might be printed with various typefaces or with unpretentious contrasts. How then does the OCR software read? There are two points to note to considerate how OCR software uses technology to read patterns and features. A smooth OCR program may be designed to read and observe many different fonts and patterns. When any of the versatile patterns are presented to the software, it uses technology to convert it to machine-readable text accurately so it becomes searchable. Be that as it may, this is most likely not a quickened arrangement on the grounds that there are unlimited text styles in presence, and furthermore the penmanship of various people may not fit in with set patterns.

ICR, or Intelligent Character Recognition, is an upgraded version of OCR and it uses feature extraction technology to spot and ‘understand’ characters. A set formula may be enforced to check if the conferred data conforms to a pattern. For example, to read the letter A, the software may check if two angled lines are present that meet at the top with a horizontal line bisecting both at the center.

Benefits of OCR

1. Searching and Manipulating Data

The capability of OCR to create a text version of scanned documents makes it achievable to search for text and locate sections of the document by searching for keywords. It also allows you to edit the document with a word processor.

2. Help for the Blind and Visually Impaired

Screen readers can interpret machine-readable text and read out the words on screen so visually flawed people can understand.

3. Faster Data Entry

Normally, OCR can greatly improve the effects and effectiveness of office work. This is because in most offices, there is a lot of scanning with a high number of documents, and there is a great need for high productivity and more efficient processes.

The Immense Impact of OCR

OCR (along with paperless document management) can make life smooth in many ways. Here are a few of the biggest benefits we stand to gain from the product:

  • Printed matter can be stored accurately, easily, and in a highly compact manner after using a scanner. A room full of books and articles can be diminished to nothing more than images on a thumb drive.

  • In businesses, OCR technology brings about powerful solutions inefficiency. Analytically, of the 12 minutes needed by an employee to create and process a document, 9 minutes are spent in locating and getting it ready for use.

What OCR Software Can Do for You

If you want your image-based or scanned PDF to be searchable and adaptable, all you require to do is find the right OCR software, like PDFelement. This multilingual OCR software can undoubtedly detect and observe text from scanned documents, enabling you to easily copy, extract, search, and edit content.

In inclusion to OCR, PDFelement also accommodate PDF creation, editing, and conversion into one package. You can alter PDF content, pictures and pages, comment on and comment PDFs, or convert PDF to or from different other document types.
