QPPG_BEAT_DETECTOR - QPPG PPG beat detector.

QPPG_BEAT_DETECTOR detects beats in a photoplethysmogram (PPG) signal using 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)
