【摘要】 人脸检测可以应用到人脸识别、新一代的人机界面、安全访问和视觉监控以及基于内容的检索等领域,具有重要的意义。人脸检测要走向实际应用,精度和速度是亟需解决的两个关键问题。经过20世纪90年代以来十多年的发展,人脸检测的精度得到了大幅度的提高,但是速度却一直是阻挠人脸检测走向实用的绊脚石。为此研究者们也作了艰辛的努力。直到21世纪Viola基于AdaBoost算法的人脸检测器的发表,人脸检测的速度才得到了实质性的提高。该算法的发表也促进了人脸检测研究的进一步蓬勃发展,在这方面先后涌现出了一批优秀的文献。基于此,本文在系统地整理分析了人脸检测领域内的相关文献之后,从速度的角度将人脸检测的各种算法大致划分为初始期,发展期,转折点和综合期等四类,并在此基础上进行了全新的总结和论述,最后给出了人脸检测研究的一些可能的发展方向。更多还原

【Abstract】 Face detection is born, as an independent subject, of face recognition and develops with the requirement of the automatic face recognition system. Over the past ten years face detection has been thoroughly studied in computer vision research for its interesting applications, such as a face recognition system, a surveillance system and a machine interface. Whether face detection can come into use depends on the two key problems: the detection rate and the velocity together. Although the detection rate has been improving during the last ten years, the speed is still a problem to cumber face detection system from being widely used. The hard work of researchers, especially the release of the AdaBoost based classifier presented by Viola, has made the detection velocity improve rapidly. Since, the researches began to lay more emphasis on the velocity of the system and a lot of algorithms, about how to increase the speed of face detection, have been presented. Based on these rapid developments of its velocity, this paper demonstrates it from the view of velocity. The whole stage of face detection is divided into four parts according to the extent of the face-detection velocity: the initial phase, the developing phase, the turning point and the synthesis phase. After the systematical analyses of the papers in different phases, several promising directions for future researches are also proposed in this paper.更多还原
