Optical Character Recognition (OCR)
Optical Character Recognition (OCR): A technology that enables the conversion of different types of documents, such as scanned paper documents, PDF files, or images captured by a digital camera, into editable and searchable data. This is commonly used in digital archiving, where physical documents are converted into digital formats for easier data retrieval and management.
