Claim 8:
9. The apparatus according to claim 1, wherein said classification comprises: rejection of anomalous estimations by comparison with a predetermined normal value of an optical flow vector; identification of features with non-null axial motions and said classification based on a direction of a corresponding axial component with creation of a ternary graph containing three motion classes of high, low, null; identification of the direction relative to said mirror artifact graphic features integrating data obtained from said ternary graph; filtering isolated elements from binary graphs, by removing non-null elements for which there are no close elements belonging to the same class; and application of morphologic operators on the filtered binary graphs.
