What is OCR Technology?
Optical Character Recognition (OCR) is a transformative technology that converts scanned documents, PDF files, and images into editable, searchable text. Instead of manually typing content from physical documents, OCR tools automatically recognize printed characters and transform them into digital text.
How OCR Works
OCR technology follows a three-step process:
- Preprocessing: The image is cleaned and prepared for recognition (noise removal, skew correction, segmentation)
- Character Recognition: Each character is identified and matched against the software’s database
- Post-processing: Error checking and correction using context to improve accuracy
Why OCR Quality Varies
Different OCR tools use varying algorithms and technologies. Tools powered by machine learning and AI typically deliver higher accuracy, especially with challenging inputs like handwritten text or complex layouts.
