摘要
为解决某些环境图像中人脸轮廓模糊,人脸面部特征单一问题,提出基于机器视觉技术的红外与可见光人脸图像配准方法.采集红外与可见光人脸图像,对其进行直方图均衡化处理,采用Canny边缘算子方法提取人脸图像轮廓,并依据轮廓的梯度大小以及方向特征实现红外与可见光人脸图像配准.实结果表明:该方法可有效提升红外与可见光人脸图像的配准度,在无遮挡时配准度数值为0.961,在遮挡10%和20%时,配准度数值分别为0.949和0.944,由此说明该方法应用效果较为显著.
Abstract
In order to solve the problem of blurred face contour and single facial feature in some environment ima-ges,a method of infrared and visible light face image registration based on machine vision technology is proposed.Ac-quire infrared and visible face images,perform histogram equalization on them,use Canny edge operator method to ex-tract face image contour,and realize infrared and visible face image registration according to the gradient size and di-rection characteristics of the contour.The experimental results show that this method can effectively improve the regis-tration of infrared and visible face images.The registration value is 0.961 when there is no occlusion,and 0.949 and 0.944 when there is 10%and 20%occlusion,respectively.This shows that the application effect of this method is sig-nificant.
