Is there a way to detect facial features on a video?

Question

I'm trying to find out if there are any libraries or frameworks that will help with detecting facial features i.e. the eyes while video recording.

I tried using face.com api and THE CIDetector on IOS, but they only work on Images not video.

P.S. I'm developing for the iphone!

Answer 1

Why not simply extract frames from the video as it is playing and use those in the CIFaceDetector? This site has some good info on how to get frames from video files on iOS:
