Scan Tailor is an interactive post-processing tool for scanned pages. It performs operations such as page splitting, deskewing, adding/removing borders, and others. You give it raw scans, and you get pages ready to be printed or assembled into a PDF or DJVU file. Scanning, optical character recognition, and assembling multi-page documents are out of scope of this project.
Scan Tailor is Free Software (which is more than just freeware). It’s written in C++ with Qt and released under the General Public License version 3. We develop both Windows and GNU/Linux versions.
This project started in late 2007 and by mid 2010 it reached production quality. In 2014, the original developer Joseph Artsimovich stepped aside, and Nate Craun took over as the new maintainer.
Scan Tailor is being used not just by enthusiasts, but also by libraries and other institutions. A few books processed by Scan Tailor even ended up on Google Books.
Contributions from other developers are welcomed and encouraged at the Github project page.
