使用经验模式分解消除心电信号基线飘移
Abstract-The removal of baseline wander (BW) is a very important step in the pre-processing stage of electrocardiogram (ECG). Thus, a method for accurate removing the baseline wander (BW) in ECG on the basis of Empirical Mode Decomposition (EMD) is proposed in this paper. We briefly described the principles and characteristics of the EMD in Section Ⅱ. To validate the proposed method, the recording from MIT/BIH database is used. In this paper, the traditional median filter is also applied to remove BW in ECG for comparison with our ENID method. The BW correction results are detected by the QRS detection program. Our experimental results show that the performance of EMD method is very good and accurate in removing BW in ECG.
