人脸识别技术综述

人脸识别技术(FRT)是当今模式识别和人工智能领域的一个重要研究方向.虽然人脸识别的研究已有很长的历史,各种人脸识别的技术也很多,但由于人脸属于复杂模式而且容易受表情、肤色和衣着的影响,目前还没有一种人脸识别技术是公认快速有效的.本文主要讨论了人脸识别技术的一些常用方法,对现有的人脸检测与定位、人脸特征提取、人脸识别的方法进行分析和讨论,最后对人脸识别未来的发展和应用做了展望.

Research and application prospects of face recognition technology

Nowadays the face recognition technology (FRT) is a hot issue in the field of pattern recognition and artificial intelligence. Although this research already has a long history and many different recognition methods are proposed, there is still no effective method with low cost and high precision. Human face is a complex pattern and is easily affected by the expression, complexion and clothes. In this paper, some general research are discussed, including methods of face detection and location, features abstraction, and face recognition. Then we analyze and forecast application prospects of FRT.
