一种通用的红外人脸器官定位算法

A universal facial organs localization method for infrared face

红外人脸热像图是红外成像领域的研究热点之一,而对作为其基础性研究的通用红外人脸定位算法却研究的较少。利用由人脸生理结构造成的温度特异性和由温度变化形成的图像边缘,给出了一种通用的人脸器官定位算法。首先利用温度特异性定位鼻孔等温度特异性强的区域,然后以此为参考点,结合面部器官分布特点,对融合提取的图像边缘信息进行眼睛等其他器官的定位。实验结果表明,该方法对各器官的平均定位精度均达到了90%以上,具有一定的实用价值。另外,该方法不仅可以对常规的眼、鼻、口等器官进行定位,而且还可以对眉骨、瞳孔等位置进行定位。

Infrared face is one of active areas in infrared imaging,but the facial organs localization as its basis issues is lack of research.A universal method is proposed which localizes facial organs based on temperature distribution specificity and edge formed by variety of temperature.In this method,the organ which lies in strongly temperature specify zones like nose is located first,and then takes it as reference to locate other organs combined with image edge information.The experiments show that the average precision achieves 90% at least,which means that the method can be used in applications.At the same time,this method not only can locate regular eyes,nose,mouth,but also can locate brow bone and iris.So it can be used in more applications.
