Probabilistic Source Separation for Robust Fetal Electrocardiography
Figure 3
Results of source separation by the developed ISS method and FastICA for SNR of 6 dB. Each panel represents one of the three orthogonal ECG sources. In each panel, the top line represents the ECG source used in the simulation, the center line represents the corresponding source extracted by the ISS method, and the bottom line represents the corresponding source extracted by FastICA. The simulated fetal ECG recording used in the source extraction was depicted in Figure 1.
