Face tracking question

I have read the face tracking demo, is the face tracking of nuitrack can not as detail as Kinect? Kinect can get the FaceFrameSource or any motion but nuitrack just can get the face position according to the head joint of skeleton, is there right?

Yes and no.
Nuitrack uses our fully-featured face detection/recognition solution (face.3divi.com/) under the hood, so it detect and recognize faces at any position inside image internally. But as Nuitrack is initially and mainly concerned about skeleton tracking it just won’t output any face which couldn’t be associated with the corresponding body/skeleton. If customer mostly concerned about face tracking (and not body tracking) then Face SDK should be more suitable choice. But in general we are open to hear any suggestions on this part.
