Hi list!

Is it possible to do with the gimp (automatically?) what www.scanR.com does?

I'm not sure you would want it to. Seems the primary function of scanr is scanning and sending, neither of which is native to GIMP. At least I don't think so. I do see that it cleans up the image, but I suspect that's a lot of propaganda. They'll certainly show you the best efforts the software makes.

I doubt there's any software that is going to 'magically' align and correct errors in a photographed document. Really, how does it know what's a shadow verses a border or such?

I'd suggest you're probably better off sending the image with your phone to an email and then cleaning it up by hand.

Alignment is quite easy, though. Seen it on a mobile phone for business cards. It's all basic image recognition tasks (somewhat simplified, the process is formalized pretty well):

- extract primtives (e.g. the border of the card, the corners) - connect them to shapes (some kind of trapezoid, for the business card) - compare the shape with known shapes (the aren't that many different views) - if we have a match, apply perspective corrections (trapezoid -> rectangle) - if an error occured, display the message

On Linux systems Xsane, a scanner program, is a useful plugin.

Yep, it works very well. :)

John, I've been sending you e-mail but I don't know if you've been getting it. Check your junk mail folder just in case. :)

Peace...

Many of these pictures are photos of pages of books or photos of "whiteboard-drawings". What I want to do is: correct/normalize the perspective and size of the images (best "automatically") so that it makes sense to archive and/or print them.

Does anyone have an idea how to do this. With the gimp? With another software?

Hugin can be used to correct perspective very effectively, but it isn't "automatic":

Hi Birt,

You are right, clicktoscan will dewarp your images and will also allow you to upload via the site directly, via your email account, or even with your camera phone.

You can manage all your docs on line with the free account, and send them to other via email as a pdf or as a fax.

Pls feel free to pass our link to any other curious users, to try the beta, it is free for the time being.
