The correct repair of three-dimensional models is still an open research
problem, since acquiring processes (methods and technology) still have limitations.
Although a wide range of approaches have been proposed, the main
limitation is that user intervention is required to decide which regions of the surface
should be corrected. We propose an automatic method for hole characterization
enabling the classification of real and false anomalies without user intervention
by using an irregularity measure based on two geometrical estimations: the
torsion contourís estimation uncertainty, and an approximation of geometrical
shape measure surrounding the hole.
