WebApr 5, 2024 · Compared to Gaussian curve fitting, the SCF method involves fitting a symmetrical curve to the PPG waveform rather than a Gaussian function. The main advantage of using a symmetrical curve is that it can better capture the shape of the PPG waveform, which may have different slopes on the rising and falling edges.
