Abstract: Whether a driver is fatigued can be reflected by his eyes during the course of driving，so it is practical to use the information about the driver’s eyes to monitor driver’s fatigue state and among this，eye location is the key problem.This paper proposes a new method for locating the eyes precisely in face detection.The new method consists of two main parts.In first part，we use skin cluster algorithm to divide human face region.In skin segmentation graph we do geometry filter.We calculate the centroid of hole in the face region to find human eyes.In second part，this paper proposes a new eye model.A new ellipse detection approach based on Hough transform is applied to locate the irises precisely according to the face region and eye region.Experimental results show that the proposed approach is fast and reliable.
