davidy writes "I have photographed some pages of a book for reading on my PDA. This is much faster than scanning and I don't have to carry the heavy books. However, the photographed books are not as nice: curved, skewed, and shadowed, as opposed to the much flatter, cleaner scanned books. I have searched for software that can flatten the pages for better reading on the PDA. So far I have come across Unpaper and Scan Tailor. Unpaper doesn't seem to have a windows GUI, and Scan Tailor doesn't unskew well. I remember reading about Google's technique of converting books to e-books with a camera and a laser overlay. Is there any home user software that can do a similar job without the need for a laser overlay or other sophisticated (and patented) technology?"
