| Abstract(in English) | Our group has studied contour extraction methods for various face components such as lips and eyes from digital face images using the deformable template matching method. In our method, each template expressing a contour is composed of fixed number of simple mathematical functions including quadratic functions. This simple template enables us to compare component contours of various persons and to analyze statistical features of them through processing the limited number of parameters. In this paper, we propose a tooth contour extraction method using the deformable template matching, where the template is composed of four elliptic curves. Our method optimizes the parameters of the template by a local search method so that it is best fit to the edge image of a tooth, after automatically identifying the tooth region from a given teeth image. We describe the details of the proposed algorithm and show simulation results for several sample images. |
