Multi-pose face recognition based on a hierarchical model and fusion decision

摘要

摘要: 该文提出了基于层次模型和融合决策的多姿态人脸识别技术,它首先把各人脸按姿态分成几个大类,并且对各大类按人脸个体分成相应子类,然后对各个大类分别进行基于特征脸的人脸识别,最后对各个姿态的人脸识别中间结果进行融合决策得到真正的人脸识别结果,该算法同时也提供了其姿态识别结果,并且大大减小了耗时,该文算法对ORL,UMIST,Stirling数据和一些自拍数据共1200幅人脸图像进行了识别测试实验,其结果令人鼓舞。

Abstract: A multi-pose face recognition algorithm based on a hierarchical model and fusion decision is proposed in the paper. First, face images are divided into several classes based on their poses and every class into many sub-classes based on their subjects. Then, traditional face recognition technology based on eigenface is applied in the process of face recognition in every class. Finally, fusion decision is adopted to get the final result of face recognition based on the intermediate result of every class. It also, can get the result of its pose recognition and its computation time is far less than that of the traditional methods. The algorithm discussed above has been tested in the experiments of a multi-pose face database with total 100 subjects and 1200 face images, which consists of ORL, UMIST, Stirling and face database of authors lab. The results are encouraging.
