Filtering a photo of a document to look like a proper scan So there are a couple of iOS apps that "scan" documents and automatically do some processing to make the image look like a quality scan from a real scanner.

When I'm trying this on the Mac with pictures from a DSLR manually with Photoshop the results are usually not as good as what these apps achieve.

Therefore I'm looking for either a Mac app or instructions for Photoshop on how to achieve this. Or maybe even an Automator script.

Just to be clear: I do not need OCR!
You can use ScanTailor.


  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.


The program is developed for Windows, GNU / Linux, and other Unix-like systems such as Mac OS X. See Installation . You might need to build it from source though.
