What is Text Extraction?

Text extraction is the process of retrieving text from images or scanned documents using Optical Character Recognition (OCR) technology. OCR converts different types of documents, such as scanned paper documents, PDF files, or images captured by a digital camera, into editable and searchable data. This technology is widely used in various fields, including education, business, and healthcare.

How OCR Works

The OCR process involves several steps:

Image Preprocessing: The image is cleaned and enhanced to improve recognition accuracy.
Text Recognition: The software analyzes the text patterns and converts them into machine-readable characters.
Post-processing: The recognized text is further refined to correct any errors and format it appropriately.

Importance of Text Extraction

Text extraction plays a crucial role in various applications:

Efficiency: Manual data entry is time-consuming and prone to errors. Text extraction automates this process, saving time and reducing mistakes.
Accessibility: Extracted text can be made accessible for those with disabilities, allowing them to interact with printed materials.
Digital Archiving: Text extraction aids in digitizing printed documents, making them easier to store, search, and retrieve.
