Face detection:a survey
Li Zhao · Journal of Circuits and Systems · 2006
The study of face detection has been made great progress in past twenty years.And,face detection has been widely used in the fields such as security,human-machine interface,human expression and so on.The purpose of this paper is to categorize and evaluate face detection algorithms.These algorithms are categorized in three aspects,respectively,based on geometrical feature,skin color,and statistic theory.After analyzing merits and limitations of these algorithms,this paper discusses promising directions for future research.
