人脸识别是近年来模式识别、图像处理、机器视

觉、神经网络以及认知科学等领域研究的热点课题之

一。作为生物特征识别的一个重要方面, 人脸识别在

档案管理系统、安全验证系统、信用卡验证、公安系统

的罪犯身份识别、银行和海关的监控、人机交互等领域

具有广阔的应用前景。与指纹识别、视网膜识别、虹膜

识别等技术相比, 人脸识别技术在数据采集方面手续

比较简单, 使用者更容易接受。-Face recognition in recent years, pattern recognition, image processing, machine vision, neural networks, and research in the field of cognitive science, one of the hot topics. As a biological feature recognition is an important aspect, face recognition in the file management systems, security verification systems, credit card verification, security system, criminal identification, banking and customs controls, the areas of human-computer interaction has broad application prospects. And fingerprint recognition, retina identification, iris recognition technology, compared with face recognition technology in the data collection procedure is relatively simple, the user is more receptive.
