Abstract: It puts forward a new visual fatigue analysis algorithm which is applicable to detect face location and eyes state in driving at real time. The differential method is quickly used to find the target area of video. Face is positioned by skin color segmentation combining YCbCr color space. The eyelid is detected by using the gray integral projection and Hough transform in the area of face. The detected data of eyelid is analyzed, and the condition of eyes is got. Value of EOD is to judge whether the driver is fatigue combined with blink analysis. The experimental result shows that the method can locate face quickly in complex background. The value of EOD is detected when the eyes open, and real-time test of visual fatigue is improved.

Key words: driving fatigue, video, skin color segmentation, Hough transform, blink cycle
