Optical Character Recognition (OCR) is a technology that extracts or recognizes the text from digital images and scanned documents. It scraps the data using OCR on remote or virtual machines. It converts the typed or handwritten printed text into machine-encoded text—the extracted data used for the electronic business process without manually capturing it. The OCR Engines such as Google cloud OCR engine, MODI OCR engine, and Tesseract OCR engine extracts PDF data, PDF text, or text using OCR and is also used to find positions and identify documents validating data.
