[Digikam-users] Face recognition

[Andi Clemens]

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.
