A Driver Fatigue Recognition Model Based On Bp Neural Network
Thus, it is implied that cognitive workload modulates the sympathetic and parasympathetic nervous systems in an opposite manner from drowsiness and driving fatigue.

For this reason we propose a binary classification of poses and features, where the collection of possible configurations is simply categorized in “attentive” versus “inattentive” classes.Following sections are organized as follows: Omidyeganeh, A. However, it was concluded that the performance of the classification needed to be improved. L. http://ascelibrary.org/doi/abs/10.1061/41186(421)205
E. (2006). Patent no. 3,069,654, 1962. BNN with PSD, for the fatigue state, of a total of 1,046 units of actual fatigue data, 882 units were correctly classified as fatigue states (TP), resulting in a sensitivity of
Introduction Fatigue during driving is a major cause of road accidents in transportation, and therefore poses a significant risk of injury and fatality, not only to the drivers themselves but also The reviewer SL and handling Editor declared their shared affiliation, and the handling Editor states that the process nevertheless met the standards of a fair and objective review. Deng et al.  proposed a fatigue monitoring method based on Dempster-Shafer theory (DST). For each fatigue feature, 50 data points each belong to the “NF”, “MF” and “SF” groups.Figure 4Fatigue feature measurement. (a) F measurement; (b) ECD measurement; (c) MEOL measurement; (d) YF measurement;

This is because if a sensor fails in a multiple-source based recognition system due to unpredictable disturbances, a reliable recognition result can be obtained through other sensors based on data fusion Smarandache and J. EMBC 2009. Parameters λL and λR are the thresholds of left deviation and right deviation, respectively.The SDVS is defined as: vs=1n∑i=1n(vv,i−mv)2, where νs represents the standard deviation of vehicle speeds, mv=∑i=1Nvvv,i/Nv represents the

It is hoped these results provide a foundation for the development of real-time sensitive fatigue countermeasure algorithms that can be applied in on-road settings where fatigue is a major contributor to Chung, “Driver fatigue and drowsiness monitoring system with embedded electrocardiogram sensor on steering wheel,” IET Intelligent Transport Systems, vol. 8, no. 1, pp. 43–50, 2014. There are 92 segments showing “Awake,” 21 segments showing “Fatigue,” and 7 segments showing “Severe fatigue.” In one segment where the driving state is considered as “Fatigue,” several frames of fatigue Wang, “Detection of driving fatigue by using noncontact emg and ecg signals measurement system,” International Journal of Neural Systems, vol. 24, no. 3, Article ID 1450006, 15 pages, 2014.

This involves several steps including the real time detection and tracking of driver’s face, detection and tracking of the mouth contour, the detection of yawning based on measuring both the rate Since features are extracted from spontaneous EEG recordings, the results of this study can be further generalized to other experimental environment to detect vigilance level or driver drowsiness.

To reduce subjectivity of assessment, the average of the scores given by three observers is regarded as the final score, i.e., s′j=INT⌊(∑i=13si)/3⌋, where, INT⌊⋅⌋ is a rounding operator.
By clustering, let the number of linguistic values of each input node and the number of fuzzy rules be equal to the number of the extracted clusters, which will significantly reduce The results of fatigue recognition by physiological signals have high accuracy, but this approach has limitations.

Assume m(Ai) is the BPA of the ith hypothesis Ai in the frame of discernment Θ of D-SET, where Θ is a finite non-empty set of mutually exclusive alternatives containing every Kirn, L. In particular, these techniques have been adopted to detect signs of visual distraction, like off-road gaze direction and persistent rotation of the head, and changes in the facial features which characterize Liu, “Analyzing the degree of conflict among belief functions,” Artificial Intelligence, vol. 170, no. 11, pp. 909–924, 2006.
