OCR: optical character recognition It is a technology that has revolutionized the way written information is processed. Although it may seem complex, it is simply a system capable of recognizing and converting the characters present in an image or scanned document into text. Using advanced algorithms, OCR allows computers to interpret and manage information that could previously only be read by humans. This technology has opened the door to a wide range of applications, from the digitization and search of documents to the creation of automatic reading systems for people with visual disabilities. In this article, we will explore in detail what OCR is, how it works, and what its most common uses are.
