Optical character recognition (OCR)

Optical Character Recognition (OCR) is a technology that enables text to be extracted from images or scanned documents and converted into editable, digital data. OCR is particularly useful for digitizing printed or handwritten documents and is used in many industries.

Basics

OCR software analyzes an image and identifies characters, words, and phrases it contains. The recognized characters are then converted into text form that can be edited, searched, or exported to other formats such as PDF or Word. Modern OCR technologies often use machine learning and artificial intelligence to improve the accuracy of text recognition.

OCR advantages

  • Save time: OCR speeds up the process of data entry and management by minimizing manual work.
  • Accuracy: OCR technology can be very accurate, especially when working with high-quality scans and clear text.
  • Accessibility: Converting printed material to digital formats makes the text searchable by search engines and more accessible to people with visual impairments.

Fields of application

  • Document management: Scan and archive contracts, invoices, and other business documents.
  • Libraries and archives: digitization of books and manuscripts for online accessibility.
  • Automated data acquisition: In logistics for capturing delivery information and in manufacturing for quality control.
  • Education: Scanning and digitization of school and study materials.

Challenges

  • Document quality: Poorly scanned or damaged documents can affect the accuracy of OCR technology.
  • Fonts and layouts: Some OCR systems may have difficulty recognizing unusual fonts or complex layouts.
  • Language support: Not all OCR systems support multiple languages, especially those with non-Latin writing systems.

Conclusion

Optical character recognition is a transformative technology that increases efficiency in many areas and offers new opportunities for digitization and accessibility of information. As with any technology, there are challenges and limitations, but the continued development and improvement of OCR systems makes it an indispensable tool in the modern data landscape. In AI-powered document analysis applications like MAIA, OCR is an indispensable feature that can significantly improve response quality.
