Tracking faces only

I am using nuitrack instance API to track facial features in realtime. Currently it does not track without seeing the full skeleton. I am only interested in the face. Is there a way to get it to recognize faces without the full skeleton?

for that you better try their Face Recognition SDK (it is separate product)

The facesdk seems a bit overkill and pricey for my project. We only need to support face feature capture in one location with one camera and do not need face recognition database. Facesdk seems to be primarily for face recognition and is priced accordingly.
