Bullet Identification Based on Feature Enhancement and Local Matching of Striated Toolmarks by Image Analysis

Abstract

Bullet identification is the difficult work that only specialists can do. It requires a high level of skill and takes a long time. So we are trying to assist appraising workers by using an image processing technology. In this paper, we propose a method to express the similarity between two bullets numerically and to estimate whether two bullets were fired by the same firefream.
