Abstract(in English) | This paper introduces a novel system for person identification from shadow images of walking person projected by invisible lights, and a shadow database of walking people. In general the correct classification rate of person identification is better when multiple cameras from different viewpoints are used, but most of conventional methods have used one camera, because of (i) easy installation in real environments, since there is no need to synchronize cameras, (ii) reduction of calculation costs. In the proposed system, we obtain the advantages of multiple viewpoints but with a single camera. More specific, we install multiple infrared lights to project shadows of a subject on the ground and a camera with an infrared transmitting filter to the ceiling inside of a building. Shadow areas, which are projections of one's body on the ground by multiple lights, can be considered as body areas captured from different viewpoints, so the proposed system enables to capture multiple body areas from only one camera. We collect a shadow database consisting of 28 people with this system, and we extract features from shadow areas by spherical harmonics, followed by identification of the subject. Experiments using the gait database show the effectiveness of the proposed method. |
