利用小波包提取脉象信号特征的方法

A Method to Extract the Feature of the Pulse Signal Based on the Wavelet Packet

将基于小波包分析构造特征向量的方法应用到脉象信号分析中,阐述了构造方法,给出了实验数据。构造的特征向量具有较好的重复性与稳定性,可以较有效地区分正常人与心脏病人。

Based on the wavelet packet analysis, the method to construct vectors is applied to the pulse signal analysis. The method is expatiated and the data are showed. The feature vectors extracted by this method are repeated and stable, and they differentiate the normal and the diseased effectively.
