Research on fatigue driving detection using forehead EEG based on adaptive multi-scale entropy

Abstract

Fatigue driving is one of the main factors that causes traffic accidents. In the current non-linear analysis methods, the entropy feature extraction methods can be well applied to detection of driving fatigue. However, all of these methods analyzed the EEG data on a single scale signal and there is also no effective way to determine the signal multi-scale information. In addition, most of the current researches choose all the electrodes, which is not conducive to practical application. Based on the forehead EEG data, an adaptive multi-scale entropy feature extraction algorithm is proposed by combining with an adaptive scaling factor (ASF) obtaining algorithm and entropy feature extraction method. Firstly, ASF algorithm is used to extract the scale factor of the signal. Secondly, this factor is used to reconstruct the signal to get new signal data. Finally, the entropy features are extracted for classification. The experimental results show that the proposed adaptive multi-scale entropy feature algorithm is effective in the detection of fatigue driving based on using forehead EEG data. So the effectiveness of this feature extraction algorithm is proved.
