Optical Character Recognition

Are you getting frustrated with having to type the whole text to extract it from a picture? Spending time translating an image to text is a significant oversight in this day and age of technology.

To convert a photo to text, it shouldn’t take more than a few seconds. Fortunately, tools are available nowadays that take just a few seconds to turn an image into words. Additionally, everything can be done perfectly accurately.

To extract text from pictures, many software make use of optical character recognition (OCR).

So, in this article, we will look at Optical Character Recognition technology and how it plays a vital role in document imaging. Let’s get started!

What is OCR?  

OCR (Optical Character Recognition) is a technique that converts any picture having hand-lettered or printed legible text into a readable text document.

The recovered text may be further modified using word processing software such as Microsoft Word.

If you cannot identify a friend’s handwritten text, this tool will assist you in doing so. Most significantly, you can convert any image into text without worrying about how the image was initially formatted.

How does it function?

Image to text converter is used to convert a scanned picture into text by analyzing the patterns of light and dark that makes up the letters and digits in the image.

For OCR systems to recognize characters in various typefaces, rules must be implemented to assist the system in matching what it sees in the image with the appropriate letters or numbers.

You must scan the document in its most apparent possible form for Image to Text converter to perform effectively. For example, text that is blurred or markings on the copy may cause mistakes.
