An individual identification by using an angled facial data

In this paper, the authors propose a method of identifying individuals using the angled facial image obtained from a CCD camera. The authors believe that they can obtain more effective data for identifying faces by setting the CCD camera at an angle to the faces concerned. When a CCD camera like this is set, they believe that effective information is able to be obtained from the large region, of one side of the face, the information of nose height which is one of three dimensional facial information and the cheek undulation which is part of the outline of their profiles. Before the identification of the face is carried out with the use of this angled image data, calibrations relative to the positions, the scales and the directions of the faces of the subjects at the time the data were obtained. The input data for identification is composed of the following; the edge image of the certain region around the right eye; the gray image of the certain region around the mouth; the shape of the nose; and the shape of the outline of the angled face. Experiments using the experimental system are performed to demonstrate the efficacy of this method and the experimental results are shown
