unpaper and Hugin

Post by Kirtai »

Hi,
I was wondering if anyone had used unpaper or hugin in their scanning workflow.

I haven't tried them yet since I don't yet have a set of scans to work on (still don't yet have a scanner made) but was hoping someone else has experience with them.

Unpaper http://unpaper.berlios.de/ is a tool for "post-processing scanned and photocopied book pages". It's capable of splitting/joining single and double page images, deskewing, centering, black & grey removal and so on. The user manual is at http://unpaper.berlios.de/unpaper.html

Hugin http://hugin.sourceforge.net/ is different, it's a panorama stitching tool but it's capable of merging flat images from scanners. I envision this being used to combine scans of art books or comics with images that span double pages. There's info on doing this at http://hugin.sourceforge.net/tutorials/scans/en.shtml

If anyone does try out these tools and it works for them, I'd appreciate knowing :)

I have tried to use Hugin for lots of different non-panoramic things, including joining flat scans. I found that it was a pain in the ass to use Hugin for that, generally. I have access to Adobe Photoshop CS4, and the "auto-align" and "auto-blend" layers is far easier to use. That said, you could certainly get good results out of Hugin if you were more patient than I am, or you needed Open/Free software.

PS. Welcome to the forums!

Hmm, I don't have Photoshop so I'll just have to put up with it :(
I believe that hugin can find the control points automatically but it needs a separate tool for that since the process is patented in some countries.
I'll see what I can do with them once I actually get suitable pages :)

Thanks :)
