摘要
实时性一直是嵌入式指纹识别系统开发的主要衡量标准,如何对指纹图像进行快速、准确处理是指纹识别系统的关键所在。针对ARM处理平台提出一种改进的指纹特征点提取算法,该算法的快速性和准确性已在ARM主建平台上得到了验证。
Real-time has always been the main criterion for embedded fingerprint identification system developing. How to process the fingerprint image fast and accurately is the key to fingerprint identification system. An improved fingerprint feature extraction algorithm based on ARM was presented, and this algorithm had been proved to be fast and accurate.
