Hey José,
I'm considering to apply to GSoC this year, and if I do, I would like to
improve the status of scanning and optical character recognition in KDE; being
more specific:
What I want to achieve
--------------------------------
...
So... to sum up: it was/is easier to produce good djvu documents with
propietary software. I want a KDE'ish program to replace the expensive
"Document Express".
Thats a very ambitious target.
Some technical details
--------------------------------
Currently we have a couple of KDE programs to scan documents: skanlite and
kooka. skanlite is quite simple (doesn't do OCR stuff), uses the modern liksane
library, it's in extragear and works fine. kooka provided more functionality in
the KDE 3 old days than skanlite today (seems it was able to do some basic OCR
stuff), uses its obsolete libkscan library, it's in playground and I don't know
if it works or not because I don't have an scanning device right now, but at
least it builds properly.
There has been a KDE4 port of Kooka, as it was KDE3 originally. That
worked quite ok.
So... looks like the tasks to do to achive my goal would be:
1. If needed, extend libksane functionality in order to make it a good
replacement for the old libkscan.
I think thats already finished :-)
2. Port kooka to the modern libksane.
Cool, but I think Kooka as an app needs much more than just a new
underlying lib. Graphics apps nowadays are much more cool than Kooka
ever was. So if you pick that I think you should be willing to bring
Kooka to an up to date state. However I am not so sure if there is still
a demand for that kind of app...
3. Add ocropus support to kooka (I heard with ocropus you can get the
coordinates of the texts, but I don't know for sure yet)
4. Code something in kooka to produce djvu documents.
The idea back in the days was to provide a component for OCR which can
be reused in all apps which deal with images, similar to what the
ScanService is (you can find it for example in Gwenview under the Moduls
menu. I think that would be really cool and could be a great GSOC
project imo.

Klaas
