1. A method comprising: calculating, by a processor, a geodesic distance measure associated with each of a plurality of points on a surface of an ear impression model; identifying, by a processor, a first point corresponding to a first anatomical feature of the ear impression model as a point having a maximum geodesic distance measure of said plurality of points; and identifying, by a processor, a first region, corresponding to the first anatomical feature, on said surface of the ear impression model as a function of the geodesic distance measure of said first point.
