摘要

一种心音分割与特征提取算法，将心音信号分为第一心音S1、收缩期、第二心音S2、舒张期四部分。提出了一种特征提取算法。该算法采用离散小波分解和重构方法对原始心音信号进行近似和细节化处理。

A heart sound segmentation and feature extraction algorithm using wavelets

A heart sound segmentation and feature extraction algorithm, which separates the heart sound signal into four parts: the first heart sound S1, the systolic period, the second heart sound S2, and the diastolic period. A features extraction algorithm has been developed. The algorithm uses discrete wavelet decomposition and reconstruction to produce approximations and details of the original phonocardiographic signal.
