What is OCR?

Optical Character Recognition, usually abbreviated to OCR, is the mechanical or electronic translation of scanned images of handwritten, typewritten or printed text into machine-encoded text.

Why Perform OCR?

OCR is widely used to convert books and documents such as scanned paper documents, PDF files or images captured by a digital camera into electronic files, to computerize a record-keeping system in an office, or to publish the text on a website. OCR makes it possible to edit the text, search for a word or phrase, store it more compactly, display or print a copy free of scanning artifacts, and apply techniques such as machine translation, text-to-speech and text mining to it. OCR is a field of research in pattern recognition, artificial intelligence and computer vision.

OCR systems require calibration to read a specific font; early versions needed to be programmed with images of each character, and worked on one font at a time. “Intelligent” systems with a high degree of recognition accuracy for most fonts are now common. Some systems are capable of reproducing formatted output that closely approximates the original scanned page including images, columns and other non-textual components.

Before performing OCR, the entire area on the page is selected and highlighted and no text can be searched and edited.

After performing OCR, text on the page can be selected with selecting tool, you can search and edit character, word, and paragraphs easily.
