Great - welcome!

Maybe it would be possible to use [5] as a library?
(Once it is converted from C to C++, any
improvements to [5] would have to moved over to C++
everytime ...)

Gilles has outlined a couple of the steps in
https://bugs.kde.org/show_bug.cgi?id=149485#c8
In particular the one mentioned in
https://bugs.kde.org/show_bug.cgi?id=149485#c10
looks interesting (which includes your ref. [5]).

So I think it would be good to first evaluate the
available tools. In particular it might be that
enhanced features of the original paper are not yet implemented
(if so, they might also be good to be added to the GSoC proposal).
((Actually: such overview would be best added to the BKO entry
above, so that it does not get lost; i.e. in contrast
to discussion on the mailing list ;-))

Then it will become clear, how much additional work is needed
to integrate it into digikam's editor (or a kipi-plugin, Gilles?).

Of course, you should familiarize with building
digikam from svn (for a start I would recommend KDE3, i.e 0.9.x series)

Also, I would recommend to join the #digikam  IRC channel on
irc.freenode.net, which allows for a quick discussion of things ...

Best,

Arnd
