ABSTRACT Due to a contact between the barrel and projectile as a firearm triggered, markings are printed on surface of a projectile. These marks are typical of each firearm and may be interpreted as a 'firearm fingerprint'. Typically, a firearm identification based on bullet's surface matching is time consuming and consists of two bullets (involved and standard ones), both matched under microscope comparison by experts in order to establish whether they are from the same firearm. The identification task demands computer aids due to a number of court cases involving firearms. This paper offers a method to get a bi-dimension representation of a fired bullet surface along with a method to provide quantitative features of those images. Finally, a statistical support to show differences between analyzed firearms is included.

Palavras-chave : automatic standard recognition; multivariate statistical analysis; bullet matching.
