摘要
随着信息和计算机技术的飞速发展,人脸面部表情识别技术越来越受到重视。本文综述了近年来人脸面部表情识别的研究进展。首先对面部表情识别技术的研究背景和发展历程作了简单的回顾,然后着重介绍了几种主要的识别方法,并力争从理论上对各种方法进行分析和比较,最后简单地讨论了进一步提高面部表情识别率的难点和必须考虑的几个重要方面,进而展望了人脸面部表情识别技术的发展方向。
Facial Expression Recognition technique becomes more and more important under the rapid technology improvement of information and computer. There are many research achievement on this area in recent years. In this paper, we gave an up-to-date research improvement survey of facial expression recognition. Except reviewing the research background and the development process on facial expression recognition, several primary facial expression recognition method were described and compared with each other in theory. We also analyzed the difficulty when improving the recognition rate furthermore and pointed out some key factors that an excellent facial expression recognition system should be considered as suggestion to future research.
