Main contribution of this paper is we introduced a real-time stress monitoring system which could estimate heart rate and mental state simultaneously. We measure heart rate remotely from continuous facial frames grabbed through a high-sensitivity camera, employ independent component analysis (ICA) to each frame to extract haemoglobin signals. Heart rate will derive from frequency analysis on hemoglobin sequence, finally spectrum analysis will be applied to HRVs to get powers of low-frequency and high-frequency band, the ratio of low frequency to high frequency powers will be used as a stress index to indicate whether the driver is under pressure or not. |
