There are described methods and system for determining a similarity or distance measure between a first ballistic specimen and a second ballistic specimen. The method comprises acquiring topographic data from the first ballistic specimen and the second ballistic specimen of at least one region of interest; computing from the topographic data at least one similarity score s for the first ballistic specimen and the second ballistic specimen; determining a non-match probability measure of the similarity score for at least one parameter characterizing a macroscopic and/or microscopic feature of the topographic data, the non-match probability measure associating the first ballistic specimen and the second ballistic specimen to a different source; and correcting the similarity score by determining a corrected similarity score that yields a same value of the non-match probability measure as the similarity score for a reference value of the at least one parameter.

Abrégé

There are described a method and a system for generating clusters of ballistic specimens. Using an image acquisition tool, topographic data for at least three ballistic specimens of at least one region of interest is acquired. From the topographic data, at least one parameter characterizing optimal toolmark alignment is determined for every distinct pair of the at least three ballistic specimens, each ballistic specimen having a plurality of toolmarks formed thereon. From the topographic data, at least one pairwise similarity score associated with optimal toolmark alignment is determined for every distinct pair of the at least three ballistic specimens. At least one triplet-wise consistency measure indicative of a consistency of optimal toolmark alignment is determined for every distinct triplet of the at least three ballistic specimens. A cluster analysis is conducted based on the at least one similarity score and the at least one consistency measure to generate the clusters.
