摘要
提出了基于多参考节点整体对齐的指纹节点匹配方法,该方法先用多对参考节点将两个指纹对齐,然后再评估两组节点的匹配程度·由于多参考节点分布在指纹的各个区域,多对参考节点对齐后,两个指纹各区域的对齐程度会相对均衡·实验表明,该方法能有效地提高系统的识别性能·
Proposed in this paper is a minutia matching method based on global alignments of multiple pairs of reference minutiae. These reference minutiae are commonly distributed in various fingerprint regions. When matching, these pairs of reference minutiae are globally aligned, and those region pairs far away from the original reference minutiae are aligned more satisfactorily. Experiment shows that this method leads to improvement in system identification performance.
