Abstract

This paper presents a shape-from-focus method, which is improved with regard to the mathematical operator used for contrast measurement, the selection of the neighborhood size, surface refinement through interpolation, and surface post-processing. Three-dimensional models of living human faces are presented with such a high resolution that single hairs are visible.
