I need to make a Fast Localization of Facial Landmark using openCV for Android. I am new to openCV and I was wondering if features2d can be used from openCV library for this purpose rather than using dlib or other libraries. If yes then which Feature Detector(eg: SIFT,SURF,ORBetc) will give a good result for just facial landmarks?
None of these will be particularly accurate. Try FaceTracker from Jason Saragih. It is easy to unbox and has Android and iOS ports.
