人脸检测中眼睛精确定位的研究

人脸检测在许多应用中都是重要的一个处理阶段,例如人脸识别、电视会议、人机界面等。眼睛是一个在人脸检测中极为重要的人脸特征,因此一种快速可靠的精确定位眼睛的算法对许多实际的应用是十分重要的。该文提出了一种新颖的精确定位眼睛的方法,该方法由两部分组成:第一部分,通过人脸区域分割、五官定位、人脸确认三个步骤在复杂背景中进行人脸区域的检测;第二部分,在检测到人脸区域和眼睛大致位置的基础上,用一种新的椭圆检测算法精确定位眼睛虹膜的位置。实验证明该文所提出的算法是快速可靠的。

Study on Precise Eyes Location in Face Detection

Face detection is an important step in many applications such as human face recognition,video conferencing,human computer interfacing etc.The eye is the most important facial feature in face detection.Thus,a reliable and fast method for locating the eyes precisely in an image is vital to many practical applications.This paper proposes a new method for locating the eyes precisely in face detection.The new method consists of two main parts.In the first part,extraction of human face region,facial features detection and human face verification are employed to detect the human face in the complex background.In the second part,a new ellipse detection approach is applied to locate the irises precisely.Experimental results show that the proposed approach is fast and reliable.
