摘要
本文在ECG信号检测过程中 ,将ECG信号在 3尺度上的Haar小波分解的细节信号模极大值对检测与数学形态学峰谷检测相结合 ,提出了ECG信号小波变换与峰谷检测算法 ,该算法弥补了小波变换算法对ECG信号时域特征检测的不足 。
In this paper is presented a new ECG signal detection algorithm, which combines amplitude maximum of ECG details of Harr wavelet transform decomposition at 3 level with mathematical morphology max min(peak trough) detection, and ECG wavelet transform algorithm is proposed. This algorithm improves the accuracy of detection of time domain features when wavelet transform algorithm is used.
