Definition of OCR
Optical Character Recognition (OCR) is the software tool to convert printed or written text into machine readable and editable file such as Word or Text. OCR software is required to electronically identify each character on a page (scanned, printed, or handwritten document) and then convert it into an editable format. The OCR performs character recognition by analyzing the image of each character read by the scanner and matching it to a pre-defined electronic character based file (OCR library). The quality of the OCR conversion process is dependent on the quality of the scanned image and the clarity of the characters of the image.
What are the Benefits of PDF Compression?
The Portable Document File mostly referred to as PDF is the widely used format for document sharing, transfer and record keeping for long time. Compression techniques are usually applied for PDF documents which tend to become very large when they are loaded with large amount of high resolution content such as images and videos, or more number of pages. Large PDF files delay email transfer by taking long time to attach. Downloading from web pages take up a lot of storage space and are difficult to work if the PDF size is too huge. The PDF compression software can make bulky PDF files easy to handle and help to save effort, time and cost for the user.
Advantages of Using OCR with PDF
Scanning and converting the scanned or printed PDF document into computer readable format is the chief advantage of using OCR. The OCR software also helps to detect poor quality images and errors in the PDF document while scanning. These results in accurate and high quality PDF output readable to the computer. Looking for quick information retrieval or specific text search in huge sized PDF documents is performed quickly and easily using the OCR. This saves a lot of time and manual effort invested by the user. Since PDF format is best suited for secure and efficient information exchange and distribution, using OCR doubles the output accuracy by quality monitoring during the scanning process itself.
