Study on Personal Identification Which is Stable Against the Change of Room Temperature Using Thermal Image

Abstract

Since the temperature distribution of the face varies among individuals, there is a possibility that it can be used for personal authentication. This paper proposes a method of using the high temperature region of the face, which is stable during personal authentication and resistant to changes in room temperature. The method obtained a 87% recognition rate in individual identification experiments under a variety of room temperature. In addition, this paper experimentally explains the method is stability against internal and external factors such as mental stress load and direct wind. Furthermore, combining this method with conventional face recognition methods using visible images, it will be possible to improve the authentication rate and avoid various risks.
