A Proposal of the Photograph Estimation Technique by Using Infrared Rays

Abstract

In this paper we propose a new automatic identification system. In our system, a user’s face is captured by a camera in order to identify him/her. By using an illumination difference image which is made of light coming from the right and left sides, our system can distinguish between a real person and a photograph. We describe an algorithm that detects whether the object facing the camera is planar(in the case of a photograph) or not(in the case of a real person). We propose a new technique for performing person-photograph distinction by using the surface direction image features.
