Claim 19:
20. A computer-readable non-transitory storage medium comprising instructions that, upon execution by a computer, cause the computer to carry out the following steps:
providing a 3D model of a person's head;
providing a parametric head model having second measurement points;
fitting the parametric head model to the 3D model of the person's head;
determining an accuracy of the fit of the parametric head model to the 3D model of the person's head;
determining first measurement points on the 3D model of the person's head by transferring the second measurement points defined on the parametric head model;
combining a plurality of at least some of the first measurement points to form a feature identifying a region of the 3D model of the person's head; and
fitting a model of a spectacle frame to the 3D model of the person's head based on the determined first measurement points,
wherein the parametric head model has a greater smoothness than the 3D model of the person's head.
