Infrared and visible face image registration based on machine vision technology
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.
