Questions[scanning](ubuntu)

My scanner has broken! I do have a good camera though so I've taken a few photos of the documents I want to scan... However they look like photos of paper, not scanned documents:

• Images aren't flat
• Lighting isn't even (shadows as the page warps, etc)
• Text obviously isn't processed into copy-pasteable PDF text.

They simply aren't suitable for professional use, but they're close.

I'm looking for some thing (or method) that can do any or all of the above so I can go from a number of JPG files to a single [optionally] annotated PDF of the whole thing, that's in the right format (A4 typically).

Any suggestions (short of going out and buying a new scanner)?

I want to be able to scan from the terminal and then send the scanned output to a specific directory. Can this be done from the terminal.

I have scanned a newspaper article which was larger than the scanner glass. Each page was scanned twice: the top and the bottom parts, where the middle part appeared in both images.

Is there a way to quickly match and stitch these scanned images, preferably using CLI? The panorama stitching tools I know require lengthy configuration, which is mostly irrelevant: lens size, focus, angle etc.

Hugin has a solution for this issue, but it isn't practical for batch jobs.

I'd like to scan a good amount of papers I have lying around, with the least possible hassle. I would like to convert them to images using Simple Scan, then convert them to text using OCR. Is there a good OCR app with a GUI that will give me good results at the push of a button?

Is there some easy to use program in Ubuntu that can scan many pages straight into a PDF file?
