A new method for obtaining human physiological parameters is proposed. Useful signal is obtained from the color video of human face by color channels separation of face region and Independent Component Analysis(ICA). Then Empirical Mode Decomposition(EMD)method is used to decompose the signal into Intrinsic Mode Functions(IMFs)that can reflect the life information. According to the criterion of extraction, accurate heartbeat and respiration signals can be extracted from the IMFs. Bland-Altman method is appl...
