摘要
人脸识别技术在国家军事安全、安全验证系统、视频会议、人机智能交互等方面有着巨大的应用前景;在民事和经济领域,各类金融卡、信用卡的持卡人的身份验证,社会保险人的身份验证等方面具有重要的应用价值。作为人脸识别的重要环节——人脸检测也得到特别的重视。人脸检测的目的是检测图像中的人脸并将其从背景中分割出来,其次是特征提取与人脸识别。人脸检测是一项具有挑战性的课题。虽然人类的人脸识别能力很强,能够记住并辨别上千个不同人脸,可是计算机则困难多了,它存在很多难题。
Face detection is the first step in the automatic system of face recognition and plays an important role in the system.So the researchers begin to lay more emphasis on the face detection and a lot of algorithms have been presented.This paper briefly surveys this area and indicates the current focus and various challenges we must face in our research for exploration.Finally several promising directions for future researches are also proposed in this paper.
