人脸作为图像与视频中最重要的视觉对象之一，是智能人机接口等许多应用的处理目标对象。近年来，人脸检测技术在模式识别、计算机视觉、人机交互等诸多领域引起了普遍重视。之所以人脸检测技术在当今计算机视觉等领域的研究中占有重要的地位并成为研究焦点，主要在于以下两个方面：一方面将人脸作为基本是绝对想来考虑，子等检测与定位人脸是实现人脸识别、人脸跟踪、表情识别、人联合成与人脸编码、唇读等技术的必要前提(Face is one of the most important visual objects in image and video, and it is the target of many applications such as intelligent human computer interface. In recent years, face detection technology has attracted widespread attention in many fields, such as pattern recognition, computer vision, human-computer interaction and so on. The research of face detection technology in the field of computer vision and other plays an important role and become the focus of research, mainly in the following two aspects: on the one hand will face as basic is absolutely want to consider, such as face detection and location is a prerequisite for face recognition, face tracking, face recognition, and joint face encoding, lip reading technology; on the other hand)
