| 摘 要： | 人脸的主要特征是曲线信息,提出了一种基于Curvelet变换的人脸识别算法。Curvelet变换在表达图像的曲线奇异性时,比小波变换和脊波变换能获得更稀疏的图像表示。在人脸识别中,用人脸的曲波系数来提取特征能更好地反映人脸的主要特征,文中使用支持向量机进行了识别。结果表明该方法比小波方法更有效。

| Abstract: | A feature extraction method using Curvelet transform is presented for face recognition.Contrasting with wavelet transform,Curvelet transform directly takes edges as the basic representation elements and is anisotropic with strong direction.It is a multiesolution,band pass and directional function analysis method and is useful to represent the image edges and the curved singularities in images more efficiently.It yields a more sparse representation of the image than wavelet and ridgelet transform.In face recognition,the Curvelet coefficients can better represent the main features of the faces.The simulation shows that the pro- posed method is better than wavelet based method. |
