SWT_BEAT_DETECTOR - SWT PPG beat detector.

SWT_BEAT_DETECTOR detects beats in a photoplethysmogram (PPG) signal using the 'Stationary Wavelet Transform' beat detector

Inputs

• sig : a vector of PPG values

• fs : the sampling frequency of the PPG in Hz

Outputs

• onsets : indices of detected pulse onets

• peaks : indices of detected pulse peaks

Author

• Dong Han - wrote the 'my_Vadrevu_2019_peakdet' function.

• Peter H. Charlton - did very little, just wrote this wrapper and made a few changes to how the zero-padding of the signal is performed (as commented in the code).
