基于马氏图与区域混合投影的眼睛定位方法

Method of Eye Location Based on Mahalanobis Map and Region Hybrid Projection

提出了一种基于肤色信息的眼睛定位方法,构造了区域混合投影函数。根据肤色信息计算出图像的马氏距离图,并分割了皮肤区域。将皮肤区域作为可能的人脸区域,对马氏距离图进行了区域混合投影,检测并定位了眼睛位置,确定了人脸的准确位置。实验结果表明,这种方法是有效的。

This paper proposes a method of eye location based on the color of skin, and constructes the region hybrid projection function. Based on the color of skin, the map of mahalanobis distance to skin in a given image is figured out, and skin areas are segmented. The region hybrid projection function of mahalanobis distance is used in the skin area, which is regarded as the probable face area. Eyes are located and face is detected. Experimental results show the method is effective.
