Preprocessing methods yield inconsistent HRV estimates in drivers; leaves open optimal standardization for sleepiness detection algorithms.
Do different preprocessing methods for outlier heartbeat detection and spectral transformation affect the estimation of heart rate variability indices in drivers?
Standard preprocessing methods for HRV data show low levels of agreement, highlighting the need to carefully consider preprocessing strategies when designing algorithms for driver sleepiness detection.
