“…Five studies did not report any ground-truth methods [14,19,22,26,27]. 4, twelve papers used some form of hardware-based filter to preprocess or extract the PPG signal [7,12,13,[15][16][17][18]21,22,26,27,30]. Three of the papers [18,26,30] used band-pass-type and signal averaging filters to preprocess signals before performing stress classification using ML algorithms.…”

“…One paper [27] used signal preprocessing before applying a statistical test to the PPG signal. The remaining eight papers [7,12,13,[15][16][17]21,22] used a combination of preprocessing and time/frequency domain analysis to extract RR interval and HR features. For time domain analysis, the most common technique was to determine the derivatives of the PPG signal and use them to determine the peaks and valleys of the signal corresponding to RR-intervals and heart beats [7,12,13,15,16,21,22].…”
