Human verification using 3D-gray-scale face image

Abstract

In recent years, many different techniques have been proposed to verify human face. Most of them used gray-scale image and some of them used range image. Because the two types of image include different information, their combination can increase the correct verification rate. The paper propose a human face verification method using a 3D-gray-scale imaging technique. First, we developed an effectiveness procedure for obtaining a 3D-gray-scale face image based on a 2D-gray-scale image and a range image. Then we propose a human face verification technique using the subspaee method: to verify whether the observed person is himself, distance is calculated between the face data of the person and the subspace of the registered data. In order to verify the effectiveness of our method, we applyed this method to 18 people. Tim result of experiment shows effectiveness of the method.
