人脸识别是机器视觉和模式识别领域最富有挑战性的课题之一，同时也具有较为广泛的应用意义。人脸识别技术是一个非常活跃的研究领域，它覆盖了数字图像处理、模式识别、计算机视觉、神经网络、心理学、生理学、数学等诸多学科的内容。如今，虽然在这方面的研究已取得了一些可喜的成果-Face recognition is the field of machine vision and pattern recognition, one of the most challenging issues, but also has a relatively wide range of applications meaning. Face recognition technology is a very active area of research, which covers digital image processing, pattern recognition, computer vision, neural networks, psychology, physiology, mathematics and many other subjects content. Today, although research in this area have been some encouraging results
