| 摘 要： | 根据以静脉图像拓扑结构的本质特性,提出了一种新的手指静脉识别方法.首先对细修复后的手指静脉提取交叉点;然后计算这些交叉点之间的相对距离和交叉点连线产生的夹角;最后将这2种特征融合,进行手指静脉识别.该方法结合静脉自身特征,充分利用了拓扑结构的本质属性,无须定位,一定程度上克服了图像平移、旋转对识别结果的影响.实验结果表明:该方法能够快速准确地进行身份识别,具有实际应用价值. |
| 关 键 词： | 手指静脉识别 拓扑结构 特征融合 相对距离 角度 |

| Abstract: | According to the essential characters of the image to po logy,a finger vein recognition method was proposed.The intersectant points fro m the repaired and thinned finger vein image were extracted.Then the relative d istance between the intersection point and the angle produced by the intersectio n point connections were calculated.Finallythese two features were combined for finger vein recognition.This method combined with the self characteristics of finger vein which make full use of the essential attribut... |
