and the same in english, because not all of us understand dscherman:
is it possible to use the face detection-functionality of the open cv library within vvvv. how can i get this into vvvv?
yes and no. it’s not out of the box - not natively supported. but no problem to integrate it with a little programing skills. you can write a freeframe-plugin, that links arbitrary libraries, so open cv for example.
see the links in the post above for further information.
