Version: (using KDE 3.5.9) OS: Linux Installed from: Gentoo Packages It would be very nice if photo's could be automatically tagged by using face recognition techniques. All your photo's could be scanned for people, then grouped by similarity and tagged all at once. If already tagged people are found, they could be tagged without user intervention. Would be very nice!
Got a library for face recognition?
Maybe OpenCV: http://opencv.willowgarage.com/wiki/ ?
I believe digikam already uses this library to perform automatic red-eye correction...
Face Detection is easy, OpenCV does this using Haar filter. Face recognition on the other hand is very very very hard. I am pretty positive OpenCV doesn't have this feature, of face recognition, yet. Although if anybody know of any other non proprietary library that provides that support, would be interesting to have a look at that.
I had a look around the internet for something suitable, first of all apparently IPhoto 9, I think, has this face recognition technology. But I guess Apple just bought the company that developed it originally, because I just can't find anything about it on the internet. With regards to open source equivalents, there is libFace, http://libface.sourceforge.net/index.html, but that is in preAlpha and doesn't look it has been active for a while. Other then that, might have to write own code for it. One of the ideas is Eigen Face.
There is also a feature request for digikam https://bugs.kde.org/show_bug.cgi?id=146288 Maybe it could be implemented as a general approach (so other project could use it)
