Generally speaking, the frequency and duration of eye closed-state will increase and those of eye open state will decrease when drivers become fatigued. In this region, eyes are detected by open-eyes and closed-eyes classifiers. The level of open-eyes state is not analyzed. Specifically, when the system misses the target using the front face classifier, right deflected face classifier is called firstly to re-detect. Detail results are presented in Table 1. And extra tasks of alert and vigilance TAV [ 23 ] were exerted in order to ensure subjects concentrating on driving highly during the experiment. However, all above methods must use some special and extra equipment. The result could be open-eyes state, closed-eyes state, face exception, and eyes exception. Compared to the traditional style, the speed can be increased by half or more to meet the requirement of real time.
Driver fatigue is the major cause of traffic crashes and financial losses. This paper presents We define an accumulated sum of intensity from the origin as: image Figure 5: Screenshot for the Fatigue Sensing application in detection mode.

In this paper we provide an application that alerts the driver if his eyes are closed for more than 3 How to effectively monitor and prevent driver fatigue driving has much. E. Eye analysis. Above are some examples of using an "ordinary".
The drivers of the development of these features can be The application for these systems are not only limited to.
Comparison results with our method and the traditional method. Each frame contains human face. During this period, drivers should adjust device and body posture to make sure that the system could accurately identify faces and eyes.
Therefore, it is feasible to transplant our fatigue detection system based on machine vision into smart devices. Third category is methods based on vehicle state. Table of Contents Alerts. Steps of Adaboost Algorithm.
One of the most popular options is Drowsy Driver, an android app that. Research on driving fatigue detection is becoming a popular issue all over the world.
. Integral image is defined as follows: for a point in an image, In practical application, reasonable scaling of pictures has little effect on. Regulations may prescribe minimum standards and have a general application or they may define specific requirements related to a particular hazard or.
Moreover, the system is transplanted into smart device, that is, smartphone or tablet, due to its own camera and powerful calculation performance.

Six subjects were asked to implement driving tasks for long enough time to become fatigued finally. Only two eyes states open and closed can be detected in this system. In this region, eyes are detected by open-eyes and closed-eyes classifiers.
A System of Driving Fatigue Detection Based on Machine Vision and Its Application on Smart Device
Thus, histogram equalization is the next important step. The first row shows the results which were detected by the front face classifier marked with white rectangles.
Finally, the conclusion is presented in Section 5.
