-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 disaligned centering and rotation of pages and will automatically
-straighten each page by rotating it to the correct angle. This process is
-called "deskewing". Note that the automatic processing will sometimes fail.
-It is always a good idea to manually control the results of unpaper and adjust
-the parameter settings according to the requirements of the input. Each
-processing step can also be disabled individually for each sheet. Input and
-output files can be in either .pbm, .pgm or .ppm format, thus generally in
-.pnm format, as also used by the Linux scanning tools scanimage and scanadf.
-Conversion to PDF can e.g. be achieved with the Linux tools pgm2tiff, tiffcp
-and tiff2pdf.
