Infrared image has a lot of advantages,such as strong anti-interference,independence to visible light source，defendence from camouflage.These advantages help infrared image face recognition to a large extent to make up for the shortage of visible image face recognition.Joined infrared images of the characteristics of face recognition,infrared image face recognition method based on improved 2DPCA was proposed in this paper.The method joins the Fisher thought in the feature extraction,and remedy traditional 2DPCA flaws.Experimental results show that the recognition method workable and has good partition capability.
