| 摘 要： | 本文介绍一种基于小波变换的心电信号基线漂移去除方法。该方法利用小波变换多分辨分析的特性,将含噪声及基线漂移心电信号进行多尺度分解,结果表明,某尺度下的分解信号较好地反映了心电信号基线漂移,在重构过程中可直接将其去除。

| Abstract: | A wavelet transform based method to correct baseline driftin ECG signals is introduced in this paper. Using the multiresolution properties of wavelet transform,the ECG signals,containing noises and drifting baseline,were decomposed into multi- scales. Results obtained showed that the baseline drifting is represented in one ofthescales,and we can remove dircetly in thecourse of reconstuuction. Then we can get the baseline corrected ECG signals easily. |
