Abstract: An approach towards simplified models of human faces, given 2D images, is proposed in this paper. The tool involves the utilization of the 2D views -upon which certain protuberant points are automatically detected- and the adaptation of a generic 3D head model (polygon mesh) according to the information gained by the available views. This mesh provides shape information which -combined with texture information- efficiently describes specific 3D human faces. Issues related to luminance differences and rotation variations between the available views, are successfully dealt with within the texture map creation process. A set of localized transformations is also applied, in order to preserve the continuity of the human head surface. Besides this, the problem of using a minimum organic model representation is addressed. The aspect under which this issue is verged upon, is that of the solution of a trade-off problem between low computational complexity and high approximation quality.
