Human face recognition using facial feature detection techniques

This paper is a study and analysis on face recognition techniques using facial feature detection techniques, taking into consideration the different variations, advantages, disadvantages and accuracy of the methods used. The recognizing the human face is simple task for a human being even seeing a person after several years. But doing the same task by a computer is not simple because the computer will have problems in the recognizing the human face if there is a change in the facial image like, lighting conditions, complex background, pose and occlusion. Still recognizing faces in images is an emerging trend of research in image processing streams.
