<p>A method of identifying characteristics of a target, marking object comprising the steps of: providing a subject, marked article having a surface having markings caused by a marking surface of the target, marking object; obtaining a 3D dataset corresponding to a 3D virtual model of the surface of the subject, marked article by means of a sensor; extracting from dataset by means of a surface segmentation analysis data indicative of a class of the target, marking object and storing said data in the database; extracting from the dataset by means of a surface wavelet filtering operation data corresponding to one or more individual characteristics of the target, marking object and storing said data in the database.</p> |
