Suddenly I'm drooling over my breakfast!

@Danilo: thank you! I guess one step further ... is it possible to compare faces with opencv for face recognition?

There is no function CompareFaces(image1,image2) if you mean that.

OpenCV Wiki: Face Recognition using OpenCV:

Face Recognition is a very active research area specialising on how to recognize faces within images or videos.
Face recognition compliments Face Detection.
Face Detection is the process of finding a 'face' within images or videos and Face Recognition is the process of matching
the detected 'face' to one of many the faces known to the filesystem.

Your system must 'learn' to recognize faces. It needs to build a database of images and associate it with a name,
extract special features etc...

It is not as easy as just comparing two images. Not to speak about comparing it pixel by pixel...

I hoped about something like GetFaceFingerPrint(image)
http://docs.opencv.org/trunk/modules/co ... c_api.html
and the Face Recognition Library looks interesting, but it blows my little single brain cell away...
