Extracting Text from Images Using an Image-to-Text Converter

Introduction to OCR and Image-to-Text Conversion

With the rapid advancement in technology, converting images into editable text has become an everyday requirement, especially in the context of digital documents and scanned materials. Optical Character Recognition (OCR) is the methodology used to extract text from images. There are several image-to-text converters available, and one of the most popular and open-source options is Tesseract. This article will explore the benefits, limitations, and how to use Tesseract for text extraction.

What is OCR and How Does It Work?

Optical Character Recognition (OCR) is a technology that enables machines to read and extract text from images. This process involves scanning a document image and identifying the characters, which are then converted into digital text that can be edited or searched in a computer system. OCR software is widely used in various applications, such as document scanning, digitizing paper archives, and converting scanned documents into searchable formats.
