Photo Scanner
« on: October 21, 2012, 03:39 AM »
Photo Scanner is a software to transform your handshot images IE. into Din A4 PDF documents.

Web page for detailed information and Download

The idea to this software came as I switched to Windows 7 and the driver support for my good old hardware scanner ran out. Since then I decided to scan with my cellphone, because the 5Megapixels had a perfect quality in scan results. The problems were the lightning and the perspective - so I began to write the Photo Scanner to correct these problems in post. I no longer had to worry about the perspective as long as the document was fully visible and the light doesn't matter that much.

I am developing this tool in my sparetime so anyone is welcome to write mini-review  ;)

I am opened for any comments and suggestions.

Great tool :Thmbsup:

I am opened for any comments and suggestions.
Can I suggest I create a Dutch translation for you? If yes, please send (PM) instructions 8)

That tool looks very nice. Coincidentally, I have run into similar problems lately while cropping photographed pictures. Simple perspective removal was not good enough in some case, because the crappy, tiny lens of some digital cameras (and I suppose every smartphone) actually turn straight lines into curves  :(.

Here is a provocative suggestion: What if you dropped the interior control handles and only had 4 handles in the corners and 2 addition handles on each edge? That would make the set up from user perspective much simpler. The actual algorithm would surely get much more complicated, but it may be worth the trouble. (I presume, you are using a Bezier transform or something similar now.) If the application made the assumption that the region the user designated is physically rectangular, I believe the would be a way to figure out a good transformation automatically. It will be quite hard to program, but the best things are never easy.

Hi vlastimil,

yes this is a good idea. The basics for this problem are already possible: In the "Tools" menu you can refine the raster and get more handles. The problem is that there is simply no automatic interpolation yet. If you want to correct a curve, you have to refine many handles and drag them manually - I don't suppose it because it is time consuming. I'm working on interpolation and more usability updates like zooming or rotating the raster etc. The usabilty for lens correction is not yet given. It should be possible to do lens correction and even the book fold should be correctable.
