Are there any libraries in Unity for face detection?

I am final year student and making a project on Augmented Reality Based app. I need to detect person’s face on device’s camera. I am avoiding OpenCV because it is too much of cost which I can’t afford it. Face detection should work as SnapChat does.
Thank you in anticipation.

I was doing a little research some time ago and stumbled across something called OZEKI Camera SDK, which apparently has a bunch of good stuff with object recognition, edge/line detection, etc. Maybe you could try looking into it? There’s even a tutorial series on YouTube published made by the developer.
