Preliminary Study on the Efficient Electrohysterogram Segments for Recognizing Uterine Contractions with Convolutional Neural Networks

Figure 3

An example of the EHG segment with a different duration and position corresponding to the TOCO signal. The start, peak, and end points of the TOCO signal are marked by cross (“×”). The corresponding EHG segment is divided into different durations of 10 s, 20 s, and 30 s and named 10_L1∼6 and 10_R1∼6, 20_L1∼3 and 20_R1∼3, and 30_L1∼2 and 30_R1∼2, respectively.
