| 摘 要： | 提出了一种基于两层策略的掌纹识别方法。首先提出了新的定位分割方法,提取出手掌最大中心区域以及粗匹配阶段的匹配特征。然后为精确匹配提出一种有效的掌纹线特征的提取和表示方法。设计由粗到细的掌纹识别分类器,应用粗匹配算法得到符合要求的掌纹数据子集,再利用主线特征进行精确匹配。针对250幅图片做实验,精确度高达94.67%,证明了本文算法具有良好的鲁棒性和有效性。

| Abstract: | A novel approach for palmprint identification based on a two-stage strategy is proposed. First a new method for palmprint alignment and segmentation is presented.The largest center area of the palmprint is extracted as the region of interest(ROI),and geometric features are extracted as the matching features of rough matching.Then a new approach of line feature extraction and representation is proposed for exact matching.Palmprint identification classifier from rough matching to exact matching is designed,in... |
