Abstract:

An eye states recognition method based on eyelid curvature and fuzzy logic is proposed in this paper. Firstly, the upper eyelid is located using the t echnique of image processing, then its curvature is calculated. Finally ,we can get the final result of the state of the eye by using a fuzzy logic method. The result shows that this method can get a high accuracy.

Key words: （edge detection, eyelid curvature, fuzzy logic）
