Does empirical mode decomposition improve the accuracy of baseline wander removal in ECG recordings compared to a traditional median filter?
Empirical mode decomposition is an effective and accurate method for removing baseline wander during ECG pre-processing.
Na et al. (2007) studied Baseline wander in ECG. Empirical mode decomposition (EMD) vs. Traditional median filter was evaluated on Removal of baseline wander (BW) in ECG. Empirical mode decomposition (EMD) accurately removed baseline wander in ECG signals, showing good performance compared to the traditional median filter.
