Open the PDF in your PDF reader and place your cursor over the text: if the cursor turns into “I-bar”, it means you are dealing with text if it turns into “cross-hairs”, it shows the presence of an object instead of text. Scanned PDF is not searchable and the text within can’t be selected, edited or marked. When you scan a printed document with a scanner to a PDF, or convert images of various formats into a PDF, what you get is “image-only” PDF with locked snapshot-like images instead of underlying text layer. Scanned PDF files (Image-only PDF) is something different. The images in a true PDF can be resized/moved/deleted as well. Users can search the textual contents in a true PDF and select/edit/delete them – quite similar to the way you make changes to a Word document or other editable format files.

Some systems are capable of reproducing formatted output that closely approximates the original page including images, columns, and other non-textual components.PDF is one of the most favorite formats for its ability to retain document integrity. Advanced systems capable of producing a high degree of recognition accuracy for most fonts are now common, and with support for a variety of digital image file format inputs. OCR is a field of research in pattern recognition, artificial intelligence and computer vision.Early versions needed to be trained with images of each character, and worked on one font at a time. Optical character recognition or optical character reader (OCR) is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo (for example the text on signs and billboards in a landscape photo) or from subtitle text superimposed on an image (for example from a television broadcast).Widely used as a form of data entry from printed paper data records – whether passport documents, invoices, bank statements, computerized receipts, business cards, mail, printouts of static-data, or any suitable documentation – it is a common method of digitizing printed texts so that they can be electronically edited, searched, stored more compactly, displayed on-line, and used in machine processes such as cognitive computing, machine translation, (extracted) text-to-speech, key data and text mining.
