Face detection and its applications
Sunita Roy · 2013
In the past two decades, face detection has been proven as the most interesting research field from the domain of image processing. In this paper, we are going to describe some important aspects of face detection, which are very much useful in many applications like face recognition, facial expression recognition, face tracking, facial feature extraction, gender classification, identification system, document control and access control, clustering, biometric science, human computer interaction (HCI) system, digital cosmetics and many more [1]. Before that, I would like to focus on some well-known face detection techniques [2] and then some feature detection methods because until and unless we extract the important features (eyes, nose, mouth) from a face we won‟t be able to uniquely identify the person properly.
