人脸识别属于生物识别的研究领域,是模式识别的一个重要研究方向,特征抽取是解决人脸识别的关键问题。通过对各种特征抽取技术和方法的分析比较,认为光照和姿态是影响人脸识别效果的两个主要因素,提出了人脸识别的解决思路和今后的研究趋势。
Face recognition is one of the hot topics in the field of pattern recognition, and it belongs to biometrics. In this field, feature extraction is one of the key steps. In this paper, illumination and pose are considered to be the two main factors which influence the face recognition after a comparative study and analysis of various techniques and different methods of feature extraction. The methods of solving the problem and the research trend of face recognition are also proposed.
