[Retracted] Edge-Enabled Heart Rate Estimation from Multisensor PPG Signals

Figure 6

The computation procedure of the HRP, which includes two major components: establishing HRP and abnormal IHR removal. In the panel bottom, we show the raw PPG signals and the computation of RR intervals and IHRs. In the PPG signals layer, the blue signals are collected from the left wrist area. Similarly, the red one is the right wrist PPG signals. RR interval and IHR in each cardiac cycle are in one-to-one correspondence. All the IHR results constitute an HRP.
