Heart Rate Detection using a Contactless Bed Sensor: A Comparative Study of Wavelet Methods

Contactless monitoring of vital signs, e.g., heart rate (HR) attracts the researcher's attention due to its convenience and affordability. Among others, under-mattress ballistocardiogram (BCG) sensors have proved effective for contactless remote monitoring of HR. Nevertheless, HR detection from BCG sensors is a challenging task because the signal morphology can vary between and within-subjects. In...
