What’s OCR?

OCR or Optical Character Recognition is a know-how that identifies & acknowledges textual content inside scanned paperwork, pictures or pictures. OCR know-how powers instruments that may extract knowledge from PDFs or scanned paperwork by changing it into machine-readable textual content/knowledge that may be edited, displayed, searched electronically & saved extra conveniently for additional processing.

Over time, OCR has been more and more adopted in lots of document-processing workflows that beforehand relied on handbook knowledge entry. OCR is used to extract knowledge from all varieties of paperwork and ship it to different enterprise functions for additional processing.

A quick historical past of OCR

Within the early Nineteen Seventies, Ray Kurzweil based Kurzweil Laptop Merchandise, Inc., whose OCR product might acknowledge textual content printed in any font.
