unpaper is a post-processing tool for scanned sheets of paper,
especially for book pages that have been scanned from previously created
photocopies. The main purpose is to make scanned book pages better
readable on screen after conversion to PDF or DJVU. unpaper tries to
clean scanned images by removing dark edges that appeared through
scanning or copying on areas outside the actual page content.
The program also tries to detect disaligned centering and rotation
of pages and will automatically straighten each page by rotating it
to the correct angle.
