Description : 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. Additionally, unpaper might be useful to enhance the
: quality of scanned pages before performing optical character recognition (OCR).
:
: unpaper tries to clean scanned images by removing dark edges that appeared
: through scanning or copying on areas outside the actual page content (e.g. dark
: areas between the left-hand-side and the right-hand-side of a double-sided
: book-page scan).
:
: The program also tries to detect misaligned centering and rotation of pages
: and will automatically straighten each page by rotating it to the correct
: angle. This process is called "deskewing".
