What is Optical Character Recognition (OCR)?

By digitizing the document’s content, text-encased image files are produced. Word processing software cannot process text in photos the same way it does text documents. By transforming text photos into text data that can be evaluated by other business tools, OCR technology finds a solution to the issue. The data can then be used to perform analytics, declutter operations, automate procedures, and boost efficiency.

What is OCR?

OCR stands for Optical Character Recognition. It is the procedure that transforms a text image into a text format that can be read by computers. Your computer will save the scan as an image file, for instance, if you scan an invoice or a receipt. The phrases contained in the image file cannot be edited, searched for or counted using a text editor. The image can be transformed into a text file with its contents saved as text data using OCR.



Applications of OCR

History of OCR

OCR was invented by Ray Kurzweil in 1974. He invented it to read text printed in almost any font. It carried on developing, gaining from advancements in computer vision, artificial intelligence and machine learning. As a result, there was an improvement in accuracy and the capacity to identify more fonts and languages. With the introduction of smartphones and mobile apps, a larger audience now has access to OCR for activities like text recognition from photos.

Working of OCR

It processes a document’s physical form using a scanner. OCR software turns the written material into a two-color or white and black version after all pages have been copied. The scanned-in image is examined for bright and dark parts, with the light areas being classified as background and the dark areas as characters that need to be identified. After processing the black regions, alphabetical or numerical are discovered. During this phase, you usually focus on one character, word or section of text at a time. Then, two algorithms – pattern recognition or feature recognition used to identify the characters.



Advantages of OCR

Disadvantages of OCR

Conclusion

With its many advantages for accessibility, data processing and document management, OCR is a powerful tool that links printed and digital text. In our digital environment, it is still a transforming tool.
