well, nothing special, i not yet studied the best method to use. So
write all possible and simple solutions to implement (no need to
review all existing way (:=))))

The best will be the faster solution to code and to run with the less
of dependencies. i know one using OpenCV for ex, which is fine since
digiKam 2.0.0 need OpenCV with face detection feature.

One goal to remember is to limit external requirements. We use already
a lots of shared libs, which increase puzzle complexity to compile and
link digiKam...
