Abstract:

A fast eye opening and closing state recognition methed is presented to solve the problem of driver fatigue detection. Firstly, we identify the face region through the skin model. After pretreatment, we carry out Gabor transform. By choosing appropriate scale and orientation parameters, the region of eye has obvious characteristics of the gray. The region of eye has obvious peak after horizontal integral projection of the transformed image, we can recognize eye opening and closing state through the peak-to-average ratio. This way breaks through the limitation that the traditional integral projection method can only location the eye. Experiments show that the accurate of this algorithm is higher, and has good robustness to the changes of illumination.

Key words: face recognition, Gabor transform, integral projection, eye state
