Have you ever been handed a printed document, taken a photo of it, and then spent an hour manually typing out all the contents? Thanks to Optical Character Recognition (OCR), those days are entirely over.
What is OCR?
OCR is a technology that analyzes an image, identifies the shape of letters and numbers, and converts them into machine-encoded, selectable text. It is the magic behind turning a JPG photo of a receipt into an editable Word document.
Current Applications
OCR is changing the way businesses operate. It is used to digitize historical archives, scan driver's licenses at airports, process bank checks automatically, and allow search engines to 'read' the text inside memes.
How Accurate Is It?
Modern OCR, powered by machine learning, is incredibly accurate—often hitting 98% or higher on clean, typed text. However, highly stylized handwritten text or blurry, low-contrast photos can still confuse the algorithm.
