中文摘要: 深入研究了二值化指纹图像细节点提取算法,针对已有算法中存在伪细节点和遗漏细节点的问题,提出了一种改进的二值化指纹图像细节点提取算法。该算法在原有提取算法的基础上,采用了形式分割图段、结合纹线方向提取、合并图段等措施。大量实验表明,该算法显著地减少了伪细节点和遗漏细节点的出现,是一种较为理想的二值化指纹图像细节点提取算法。

中文关键词: 二值化指纹图像细节点行程图段

Abstract:Inutiae extraction on binary fingerprint images is studied deeply in this article. For used minutiae extraction algorithm, there exist some false minutiaes and omitted minutiaes. A new improved minutiae extraction algorithm is proposed to solve the problem. The algorithm divides image segment, extracts minutiaes with direction and merge image segment. Through lots of experiments, the algorithm has been proved to a better minutiae extraction algorithm which can significantly reduce false minutiaes and omitted minutiaes in the extracting process.

keywords: binary fingerprint image minutiae run-length code image segment
