Buying Guide: Choosing Optical Character Recognition (OCR) Software
OCR technology (Optical Character Recognition) is essential for the digital transformation of businesses by converting paper documents into manageable and searchable digital formats. This guide will help you understand what OCR software is, how it works, the main features to consider, and will present you with free alternatives to meet your specific needs.
What is OCR software?
OCR software allows the conversion of text images (scanned or photographed) into an editable text format. This technology is crucial for businesses that digitize large amounts of paper documents, such as invoices, forms, and historical archives, to make them accessible and searchable electronically. OCR software is therefore powerful tools for document management, electronic archiving, and audit and compliance processes.
How Does OCR Software Work?
OCR software graphically analyzes the characters on an image and translates them into text characters. The process is broken down into several steps:
- Preprocessing the image: Enhancing the image quality to facilitate character recognition (adjusting brightness, contrast, removing noise).
- Segmentation: Breaking down the image into lines, words, and eventually individual characters.
- Character recognition: Identifying each character using artificial intelligence techniques or pattern matching.
- Post-processing: Correcting errors using dictionaries or linguistic rules to improve the accuracy of the recognized text.
Main Features of OCR Software
