Optical Character Recognition (OCR)

Definition

‍Optical character recognition, OCR for short, is the technical method by which printed or handwritten texts are converted into machine-readable text using image processing. This process enables computers to extract, interpret, and edit text from images or scanned documents.

Background

‍The development of OCR technology began in the early 20th century, but with the advent of digitization and improving machine learning algorithms, and artificial intelligence significant progress has been made. Originally designed to improve accessibility for blind people, OCR is now widely used in various areas.

Areas of application

‍OCR is used in numerous industries, including banking to process checks, offices to digitize paper documents, the automotive industry for license plate recognition, and retail to recognize product codes. OCR also plays a decisive role in digitizing historical archives and books.

Benefits

‍The main benefits of OCR technology include accelerating data processing, reducing input errors, saving storage space for physical documents, and improving the accessibility of information. It makes it easier to search and analyze information by turning it into editable and searchable formats.

Challenges

‍Challenges when implementing OCR include the accuracy of text recognition, particularly when the templates are of poor quality or handwritten texts. Solutions include improving image quality before processing, using advanced algorithms, and combining them with technologies such as artificial intelligence for context analysis.

Examples

‍An industrial company could use OCR to digitize maintenance manuals so that technicians can quickly search for specific instructions or troubleshooting information. Another example is using OCR in a digital spare parts catalog to automatically extract part numbers and specifications from manufacturer documents.

Synopsis

‍OCR is revolutionizing the way data from printed and handwritten sources is processed by enabling rapid, efficient, and accurate digitization. Despite some challenges, the technology offers significant benefits for companies by increasing operational efficiency and opening up new ways to manage information.
