| 摘 要： | 针对双树复小波变换(DT-CWT)不能直接提取水平和垂直2个方向特征的不足，提出一种结合DT-CWT和Gabor小波的人脸识别方法。将Gabor小波提取的0°和90°特征与DT-CWT提取的6个方向特征连接起来共同构成人脸特征向量，采用Fisherfaces方法构建特征向量的线性子空间，应用基于欧氏距离的分类器实现分类。在ORL数据库上的实验结果证明了该方法的有效性。

| Abstract: | Motivated by the deficiency of the Dual-Tree Complex Wavelet Transform（DT-CWT） for feature extraction along horizontal and vertical directions, a novel face recognition method is proposed by combining DT-CWT and Gabor wavelet. Face feature vectors are conducted by connecting the features extracted by DT-CWT in 6 directions and Gabor wavelet in the direction of 0° and 90°. Fisherfaces method is exploited to construct the linear subspace. Euclidean distance based classifier is adopted for classification. Experimental results demonstrate the validity of the proposed method with the ORL database. |
