The most prominent technology that is used for data How OCR Works extraction from images is known to be OCR tech. “Optical Character Recognition” (OCR) is a technology used to scan and convert written data in a physical document or its digital image into an editable text file—the technology functions based on advanced NLP (Natural Language Processing) algorithms.
These algorithms help the OCR tool and devices understand human-written text in an image. After understanding these texts, the tool converts them into a digital document file that a computer can read, edit, and store easily.
In this blog, we will describe the whole process of an OCR extracting text from images in detail. But before we do that, let’s discuss OCR a little more.
What is OCR Technology-A Short Overview
OCR is a technology that detects text in a digital image and converts it into an editable text file. The image can be a physical document or a digitally designed infographic (basically any image containing text).
Remember: The OCR technology alone cannot do any extraction. Experts have integrated the OCR with online tools to enable this technology for data Oman Phone Numbers or text extraction from images. These tools are known as image-to-text converting tools.
Moreover, the technology has numerous applications and has become much more advanced recently; Its core functionality is pretty simple. Now, we will discuss step-by-step how OCR turns an image into a text format.
How is text extracted from an image using OCR?
As mentioned, OCR employs NLP algorithms to understand and extract text from an image. But why use NLP? It is simple. You see, computers are not designed to understand human written language. This is because they function in binary codes.
This means that the computer will be unable to detect Albania Phone Number List the data written in human language, English, or images in the first place. The NLP algorithms that OCR uses to understand this data and compare it with the fed dataset.
If the text in an image matches the text in the dataset of an online OCR tool, it converts it into a document file in editable or electronic words.
