Face recognition

[Stephen-125]

Hello all,

I was wondering what is the state of face recognition in digikam?  I feel this
is the biggest feature that digikam seems to be missing at present.

Thanks for all your hard work.

Regards,


Stephen.

Not implemented at all, I think. Stephan, I don't think about this
feature as biggest missing, I, presonally, usually shoot photos not
to humans. This is not needed, at least for me.

And some complicated algorithm is needed to face recognition I
suppose. Open source may have problems implementing it I think.

If I am right, Picassa has this function.

Regards,

They are one entry in B.K.O about this suject with a lots of proposals...

For me too. I don't consider it an "important feature", almost for me. I'm not sure if it could be useful to me.
But, still, it would be nice to have it. :-)

I'm happy to say that you're wrong! (maybe you also will be happy to be wrong, this time) :-)
There's already an open source library that supports these features: openCV!
Look here:
http://opencv.willowgarage.com/wiki/FaceRecognition
http://www.youtube.com/watch?v=_KhP3O3GeYs&feature=related

Unfortunately, Picasa isn't open source. :-(

bye bye

PS Ok, stop now... if I look one time more at that videos, I won't be able to live without that features on my linuxbox any more! ;-)

OpenCV is not that well suited, at least not the last time I used it for the
RemoveRedEyes KIPI plugin. The face detection is not very reliable, so
implementing something from scratch (or using other libraries and techniques)
will be required.

I had to train my own classifier for eyes for my plugin, and still it is not
that reliable. And it is slow, too... face detection / recognition over the
whole digiKam database must be fast, we can not wait minutes for any result
;-)

I don't know yet how to solve this issue, but with the standard algorithms in
OpenCV this might not work very well.

Maybe it is not *needed*, it would be great though: imagine "autotagging" of
pictures containing certain people...

And maybe it would be more useful as a KIPI-thing,
accessible by even more apps ?

Just thoughts,

That sounds like a pretty good idea for a kipi-plugin, it could even tag to
nepomuk...

I'd try it myself just that I don't have the knowledge nor the time to spend
on such a project ( I've already tried  to help, as Gilles and the other devs
know but I'm not (yet) anywhere near  *helping* :( )

If you make a kipi-plugins to tags face automatically, you will not be
able to use it during camera download. It will be a waste of time to
run it after camera download, through album icon view.

For me, an integration to digikam BD core is bettre. Don't forget that
digiKam already support Nepomuk in 1.0.0

But, creating a shared lib to KDEGraphics to perform face recognition,
or more simple to implement it to nepomuk will be great...

I'm not sure I understand why it would be a waste of time. Couldn't we tag the
pictures once they already are on our database?

If it were clear from the UI that this is a set-it-and-go-to-bed
operation, then I would not mind. The computer is not doing anything
else productive while I am sleeping.

There is a feature request in BKO to integrate Digikam tags with
Kaddressbook entries.

I think it also depends what you mean by face recognition. Should it
recognize a face (any face, for automatic
zoom-to-face/center-on-face/cropping-to-face/kenburns-to-face/whatever),
or a specific face? (find all photos containing person X's face...)

I would imagine it going through the selected photos and adding tags
for the faces that it finds.
