To improve the performance of a minutiae-based fingerprint verification system,we propose a feature called direction extension vector(DEV) for fingerprint minutiae detection,each item of which can be described as maximum extension distance from a pixel in each pre-defined direction in the sub-region with the same intensity as the pixel.
为了提高基于细节点的指纹鉴别系统的性能,提出了将方向延伸向量特征用于细节点检测,定义方向延伸向量为在预先定义的各个方向上在相同亮度条件下最大延伸长度所组成的向量。
We produce a new method for minutiae detection by following the ridge-line, where the minutiae are extracted directly from the original gray-scale fingerprint images.
提出了一种基于脊线跟踪的细节点检测新方法,它直接从灰度级指纹图像中提取特征点信息,而不必经过二值化和细化过程,从而较大节约了运算时间,提高了可信度。
