    Abstract: A method and an apparatus for generating textures for a three-dimensional (3D) facial model are provided. The method for generating textures for a 3D facial model provides extracting texture coordinate from a magnification result of a predetermined central facial portion by a predetermined rate and a reduction result of peripheral portion by the predetermined rate, by substituting transformed model coordinate generated by transforming a standard model for a frontal image and at least one side face image of a face into a conversion function in order to convert the transformed model coordinate into pixel coordinate; and interpolating the frontal and side face image, which is received from a user in response to the analysis result of the transformed model coordinate, by using the texture coordinate in the unit of polygon, which is decided by the pixel coordinate, to determine the interpolation result as transformed texture, in which the central facial portion is a region established by a user with centering upon the eyes of the face and the peripheral portion is a region corresponding to the region except for the central facial portion of the face.
