“…Zhao et al [8], for example, chose a frequency band of [48,300] min −1 (instead of the proposed [30,240] min −1 ), included the energy around the third harmonic in the energy spectrum of the pulse signal (in the original implementation, only the energy around the first and the second harmonic are included), and used the same spectral window length for calculating energies around the first, second, and third harmonic (in [21], 5-and 10-bins-long windows around the first and second harmonic were used, respectively). In the case of calculating RMSE, the length of the processing window plays an important role when interpreting the results (differences of up to 10% may occur for the window lengths from 0 to 60 s [41]). The described issue results from the already exposed drawback of the rPPG research, i.e., the lack of standardized methodology [42].…”

“…In this study, we only compared four RPPG algorithms,based on traditional signal processing, deterministic methods. Future studies could incorporate more algorithms, including deep learning-based processing ones, as noted by Mironenko et al in [14]. Therefore, an important research direction is the incorporation of an adaptive sliding window size, to more efficiently allocate computing resources, specially in more complicated environmental settings, while maximizing signal quality.…”

“…Since the diffused component of incident light carries information on subtle blood flow volume changes under human skin, it is possible to analyze that component to find the small light variations in blood flow so as to obtain live data of vital signs such as the heart rate [ 53 ], respiration rate [ 200 ], blood pressure [ 201 , 202 ], and oxygen saturation [ 200 ]. However, remote BP prediction also has susceptibilities in handling noise and artifacts unrelated to the hemoglobin signals, such as makeup [ 203 ], skin tone [ 204 , 205 ], illumination [ 206 , 207 ], camera distance [ 208 , 209 ], camera specification [ 210 , 211 ], and subject motion [ 212 , 213 ]. Considering the pros and cons of using rPPG signals, several remote techniques have been developed to manipulate deficiencies using a sophisticated solution to estiTNLmate BP from the rPPG signal.…”
