摘要
针对国内外研究心音身份识别系统的现状及技术成熟度的分析,阐述了心音与身份识别之间的相互关系,总结了构建心音身份识别系统所需要的心音采集设备、心音预处理技术、特征提取和模式匹配等关键技术,提出了心音身份识别系统发展的新思路及所面临的挑战.
Based on overseas and domestic research status and analysis of technology maturity in heart sound identification recognition,the correlation between heart sound and identification was described from a technical point of view.The key technologies required for identification system implementation,including heart sound acquisition devices,heart sound preprocessing,feature extraction and pattern matching,were discussed.Besides,development conceptions and challenges of future heart sound identification recognition were presented.
