Detecting facial expressions using the webcam and as3 [question - not solution...sorr

hi community!
does anyone know if theres a way to detect facial expression in flash?
i mean not the simple motion detection. something more complex.

detecting eyes (maybe with calibrating by using markers or something)
detecting mouth (open-close)
detecting the rotation and thing like this.

i hope someone can help me with this.

thanks in advance.

greets,
marc
