Fig. 3From: Fusion of detected multi-channel maternal electrocardiogram (ECG) R-wave peak locationsExample showing the performance of the three methods. Filled black star refers to the maternal R-wave peak location obtained with the ICA$_{ACC}$ algorithm, white square means the location obtained by the ICA$_{SMI}$ algorithm, and the red lines represent the locations of the R-wave peaks detected by our fusion algorithmBack to article page
