Unpaper : Process Scanned / Photocopied Book Pages

February 9th, 2006 | Filed under Tools.

After you photocopy pages from a book or scan them, there are dark edges, and decentered or rotated pages. Unpaper is a imaging editing software which fixes that.

Unpaper is a post-processing tool for scanned sheets of paper, especially for book pages that have been scanned from previously created photocopies.

What does Unpaper do?

“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 disaligned centering and rotation of pages and will automatically straighten each page by rotating it to the correct angle. This process is called “deskewing”.

You can Download Unpaper and fix those photocopy image errors with ease.
