1. A computer implemented method for detecting anatomical features in 3D ear impressions, the method performed by said computer comprising the steps of:

  • receiving a 3D digital image of a 3D ear impression;

    obtaining a surface of said ear impression from said 3D image;

    analyzing said surface with one or more feature detectors, said detectors adapted to detecting generic features, including peak features, concavity features, elbow features, ridge features, and bump features, and derived features that depend on generic features or other derived features; and

    forming a canonical ear signature from results of said detectors, wherein said canonical ear signature characterizes said 3D ear impression.
