I have a few books in the form of PDFs, but they were just scanned from paper like any other image/photograph. They're essentially photographs of what the pages looked like. The images happen to show visible text, but the text wasn't put in the digital files as characters, so you can't do normal computer-text things with it like copy & paste, changing font face/size/color, or using the "Find" function.
Are there any publicly available programs for extracting visible text from images and putting it in computer-text form? Or have the programs that can do it all been hidden or marked with a "Come get me FBI" beacon because they'd be the same kinds of programs a hacker would use against CAPCHA?
