1. A computer assisted method for detecting surface anomalies in a three-dimensional surface model representing a three-dimensional structure, the method comprising:

  • fitting a parametric patch to a local neighborhood around a vertex in the surface model;

    computing a curvature characteristic of the fitted patch in the local neighborhood around the vertex;

    classifying curvature of a cluster of connected vertices by comparing the computed curvature characteristic to a predetermined curvature classification; and

    defining a surface anomaly as a cluster of connected vertices having a predetermined curvature classification.
