Estimation Method of Face Direction Using Three Dimensional Images

In this paper, three-dimensional image of the face is acquired by the rangefinder, and the range image is generated from three-dimensional image. The estimation method of a face direction along horizontal and vertical axis from nose position is proposed. If the direction of the face can estimated automatically, it is possible to use as a human interface. Simulation results for three-dimensional image using two acquisition methods show that the validity of the proposed method is verified.
