| 摘 要： | 心音信号是临床上有用的心脏疾病诊断工具,是一种很好的用于身份识别的方法,而在基于心音识别的系统中,提取反映用户个性特征的参数是关键问题之一.该文将Mel倒频系数的提取方法中的Mel滤波器组用小波变换后的信号频谱拼接来替代,以此提取了新的参数DWTMFC,并用矢量量化模型进行验证.实验结果表明DWTMFC参数的性能在矢量...

| Abstract: | Heart sound is not only a valuable medical diagnostic tool for heart disease,but also a useful human identification method.And in the heart sound recognition system,the extraction of parameters reflecting the personality characteristics of the users is one of the critical issues.This paper used wavelet transform and spectrum splicing to replace the original Mel filter bank to get the new parameters DWTMFC.At last of the paper,VQ model was used to verify the new parameters.The experimental results showed tha... |
