人脸检测的研究具有重要的学术价值，人脸是一类具有相当复杂的细节变化的自然结构目标，对此类目标的挑战性在于：人脸由于外貌、表情、肤色等不同，具有模式的可变性；一般意义下的人脸上，可能存在眼镜、胡须等附属物；作为三维物体的人脸影像不可避免地受由光照产生的阴影的影响。因此，如果能够找到解决这些问题的方法，成功地构造出人脸检测系统，将为解决其他类似的复杂模式的检测问题提供重要的启示。本书对人脸检测的基本问题、研究思路和方法、经典的算法和技术全方位地做了深入系统的介绍，着重介绍了作者在利用活动轮廓模型方法进行人脸检测方面的一些研究成果，指出了该领域的未来发展方向。可作为高等学校有关专业的研究生、高年级本科生、研究院所和有关单位广大科技工作者和工程技术人员的参考书。-Face detection has important academic value, face are a class of very complex changes in the details of the natural structure of goals, targets of such challenge is: face the appearance, expression, color and so different, with model variability　general sense of the person s face, there may be glasses, beard and other appendages　as a three-dimensional objects by the inevitable face images generated by the shadow of light. Therefore, if we can find solutions to these problems, successful face detection system is constructed, will address the complex pattern of other similar issues important implications for testing. Book on the basic problem of face detection, research ideas and methods, the classical algorithms and techniques in all directions to do a thorough introduction to the system, focusing on the use of active contour model in face detection method for a number of research results pointed out the future direction of the field.
