摘要 提出基于二维Gabor小波特征(Gaborface)矩阵的人脸表征方法,二维Gaborface矩阵有别于常规的一维采样特征矢量方法。对该方法的2种运用方式:整体Gaborface表征(EGFR)和多通道Gaborface表征(MGFR)进行了研究,在ORL数据库中采用二维PCA人脸识别算法进行了实验。对比实验结果表明了该方法的有效性和可行性,特别是基于MGFR的2DPCA方法实现了100%的识别率。 This paper introduces a novel face representation method based on two-dimensional Gabor wavelet feature (Gaborface) matrices instead of the conventional transformed one dimensional feature vectors. Both the ensemble Gaborface representation and the multi-channel Gaborface representation are studied and experimented on the ORL face database using two-dimensional principal component analysis face recognition approach (2DPCA). Experimental results show the efficiency and feasibility of the method, particularly, the 100% recognition rate is achieved by the MGFR-based 2DPCA.
