We are going to see how to digitize books at home with a camera. It is faster and easy. You only need a digital camera or a smartphone.
Digitizing a book is formed by two parts. The first one consists of get images of the text book and in the second part you have to treat it with an OCR (Optical Character Recognition)
Traditionally, books were scanned page by page, this is a very slow process that was complex because of the spines of the books, which curled the pages and then the OCR did not recognize the words well. So much that many people unbundled them in order to facilitate the scanning process.
