QPPGFAST_BEAT_DETECTOR - QPPGFAST PPG beat detector.

QPPGFAST_BEAT_DETECTOR detects beats in a photoplethysmogram (PPG) signal using the fast version of the 'Adapted Onset Detector' beat detector

Inputs

• sig : a vector of PPG values

• fs : the sampling frequency of the PPG in Hz

Outputs

• peaks : indices of detected pulse peaks

• onsets : indices of detected pulse onsets

Author

• Several authors have contributed to the code (see below)

• Peter H. Charlton - did very little, just wrote this wrapper (which detects peaks given the onsets provided by the code)
