摘要:
提出了一种基于图像梯度和模板匹配相结合的眼腈定位方法。利用投影函数确定眼腈区域的上下边界，然后对于眼睛睁开较大的图像根据眼球的梯度方向信息定位眼睛中心，对于眼睛睁开较小或完全闭合的情况，利用本方法中的梯度眼睛模板进行二次匹配。试验证明该算法定位准确率高，不受眼腈状态的影响，并且对头部姿态变化和焦距变化等具有一定的鲁棒性
Abstract:
A method based on step - direction and templet - matching is described to locate eyes accurately in this paper. The top and hottom edge of eye＇ s area is confirmed according to projection function at first. And then the center of eyes are located on the basis of the step direction information of.eyeball for the eyes which open widely. The eyes which open narrowly or close are located according to the two- matching with the step - templet in this method. Experimental results show that eyes can be located quite accurately without affection to the eyes＇s state and the pose of head and the focal length of camera
