| 摘 要： | 为了解决掌纹特征提取过程中,手掌的非平面问题导致的伪主线噪音信息并简化运算,对重构的掌纹图像进行了局部离散余弦变换.解决了重构后图像噪音敏感性问题,有效地区分了掌纹主线、掌纹褶纹和乳突纹.由二维主元分析算法获得较稳健的识别特征.通过香港理工大学公布的PolyU掌纹数据库的实验,同二维主元分析算法相比,小波重构与局部离散余弦变换的2DPCA掌纹识别算法正确识别率较高,识别效率较高. |
| 关 键 词： | 掌纹识别 提升小波重构 局部离散余弦变换 二维主元分析 |

| Abstract: | In order to solve the problem that the palm-print image quality is influenced by the arch of the palm-print,which caused plam-print recognition tate to descend,the noise from reconstructed image was local DCT eliminated.The palm-print principle-line,plicate-line and papilla-line were distinguished efficiently.And 2DPCA obtained robust recognition features.Experimental results on HongKong PolyU palm-print experiments show that by the method recognition rate and recognition efficiency is higher than that by 2... |
