What is OCR
Optical Character Recognition
OCR (Optical Character Recognition) is a technology for automatically recognizing text in images, scanned documents, and photographs, converting it into editable digital format.
How OCR Works
- Image preprocessing — quality enhancement, noise removal, alignment
- Segmentation — dividing into lines, words, and characters
- Recognition — matching characters against template database or neural network
- Post-processing — spell checking and context verification
OCR Applications
- Digitizing paper documents and archives
- Automating data entry from invoices and bills
- Recognizing passports and IDs
- Translating text from photos
- Searching scanned documents
Modern Technologies
- Tesseract — open-source engine by Google
- ABBYY FineReader — commercial solution
- Google Cloud Vision — cloud service
- AI/ML models — neural networks for complex cases
Benefits of OCR Automation
- Reducing manual data entry by 90%
- Minimizing human error
- Accelerating document processing
- Integration with ERP, CRM, and document management systems
