【摘要】 指纹特征提取是指纹识别技术的关键。本文介绍的方法是,指纹图像经预处理后,不对脊线做任何修复,在细化指纹图像上直接提取原始细节特征点集,然后根据图像的伪特征点的分布规律,删除伪特征点,保留真正特征点。更多还原

【Abstract】 The technique of extracting the character of fingerprint is the key of fingerprint identity. In this article, the ridge will not be mended after pretreating the fingerprint image.The muster of eigen point will be extracted directly from the thinning down fingerprint image.At last,the redundant eigen point will be deleted and the true will be reserved on the basis of the distributing rule of the eigen point.更多还原
