OCR Full Form is Optical Character Recognition.
Optical character recognition (OCR) is a technology that allows computers to read text from images and convert it into the image to text digital data. OCR can be used to digitize books, scanned documents, or even handwriting.
OCR technology has come a long way in recent years, and today there are several different software programs available that can perform OCR with varying degrees of accuracy. Some of the more popular OCR software programs include Abbyy FineReader, OmniPage, and ReadIris.
When using OCR to digitize documents, it is important to ensure that the text is clear and legible. If the text is blurred or illegible, the OCR software may have difficulty accurately converting it into digital data.

Optical Character Recognition For Blind and Visually Impaired Users
There are a number of ways that people with visual impairments can access printed material. One way is to use a scanner and special software that converts the text into speech or Braille. This process is called optical character recognition, or OCR.
OCR can be used to scan documents, books, magazines, newspapers, etc., and convert them into a format that can be read by people with visual impairments. OCR software can be used with a standard desktop scanner or a multi-function printer/scanner/copier. The scanned document is saved as an image file, and the OCR software “reads” the image and converts it into text. The text can then be read by a screen reader or Braille display, or it can be printed out in Braille or large print.
There are a number of OCR software programs available, both commercial and free. Some of the more popular ones include:
- ABBYY FineReader
- Kurzweil 1000
- Readiris Pro
OCR can be a useful tool for people with visual impairments, but it is important to keep in mind that OCR software is not perfect. The accuracy of the text conversion depends on a number of factors, including the quality of the scanned image, the typeface of the original document, and the complexity of the layout. OCR software can also have difficulty with documents that contain graphics or handwriting. For these reasons, it is always a good idea to have the original document available when using OCR.
Types of Optical Character Recognition
There are three main types of optical character recognition: 1) scanning, 2) pattern matching, and 3) machine learning.
1. Scanning involves taking a digital image of a document and then using special software to analyze the pixels in the image and convert them into text. This type of OCR is typically used for simple documents like business cards or scanned copies of ID documents.
2. Pattern matching is a more sophisticated type of OCR that looks at the shapes of characters in order to identify them. This approach is often used for handwritten text or documents with complex layouts.
3. Machine learning is the most advanced type of OCR, which uses algorithms to learn how to recognize characters from a training set of images. This approach is often used for documents in multiple languages or with unusual fonts.
Each of these three types of OCR has its own strengths and weaknesses, so it is important to choose the right approach for your specific needs. For example, scanning is generally the fastest and most accurate way to convert simple documents into text, but it may not be able to handle more complex layouts. Pattern matching can be slower but is more flexible, while machine learning is the most accurate but also the most expensive.
How To Choose Optical Character Recognition?
The process of choosing an optical character recognition (OCR) can be difficult and time-consuming. There are a few things you should keep in mind when selecting an OCR:
- The type of data you need to recognize.
- The accuracy you need.
- The speed of recognition.
- The cost.
Keep these factors in mind when selecting an OCR and you’ll be sure to choose the best one for your needs.
