Optical Character Recognition (OCR) is a technology that converts images of text into machine-readable text. It plays a crucial role in automating data processes such as invoice management and document digitisation. This guide covers how OCR works, its applications, benefits, and future trends.
How Does OCR Software Work?
Table of Contents
OCR software converts scanned documents or images into editable data, providing a clear answer to the question, ‘What is OCR?’ for businesses aiming to streamline their document management processes. It follows several key steps:
Image Acquisition: Capture the document using a scanner or camera. High-resolution images improve OCR accuracy.
Pre-processing: Improve image quality by adjusting contrast, reducing noise, and converting to black and white.
Text Recognition: OCR software identifies text by analysing character shapes and patterns. Advanced systems use machine learning for better accuracy.
Post-processing: Correct errors using spell-check and context analysis.
Output Generation: The text is exported in formats like plain text, Word, or PDF.
Types of OCR Technology
Different OCR technologies cater to various document types:
- Simple OCR: Handles printed text in standard fonts.
- Intelligent OCR (ICR): Recognises handwritten text.
- Optical Mark Recognition (OMR): Detects marks like checkboxes.
- Barcode Recognition: Reads barcodes, which contain machine-readable data.
Common Applications of OCR
OCR has become essential across industries. Key applications include document digitization, which reduces storage costs and enhances data accessibility.
- Document Digitisation: Reduces storage costs and enhances data accessibility.
- Invoice Processing: Automates data extraction from invoices and receipts.
- Data Entry Automation: Extracts data from forms, reducing manual effort.
- Language Translation: Converts printed text for machine translation.
- Assistive Technology: Enables text-to-speech for visually impaired users.
Benefits of OCR Software
Implementing OCR offers numerous advantages:
- Increased Efficiency: Automates data extraction, saving time.
- Cost Savings: Reduces manual data entry costs.
- Improved Accuracy: Minimises errors in document processing.
- Enhanced Accessibility: Converts documents into digital formats for easier access.
