Abstract
Bullet identification requires special skills and takes a long time. So novel method is expected to be developed for assisting this skillful and time-consuming work. The discrimination of two bullets needs similarity quantification of striated toolmarks most. But conventional method based on image correlation is not applicable because of lower striated toolmark similarity. In this paper, a new method based on intersection which extracts common elements is proposed to measure similarity correctly between striated toolmarks of bullets and makes it possible to extract inherent striated toolmarks of used gun. The effectiveness of the proposed method is confirmed through experiments.
