TY - JOUR PY - 2013// TI - Automatic identification of bullet signatures based on consecutive matching striae (CMS) criteria JO - Forensic science international A1 - Chu, Wei A1 - Thompson, Robert M. A1 - Song, John A1 - Vorburger, Theodore V. SP - 137 EP - 141 VL - 231 IS - 1-3 N2 - The consecutive matching striae (CMS) numeric criteria for firearm and toolmark identifications have been widely accepted by forensic examiners, although there have been questions concerning its observer subjectivity and limited statistical support. In this paper, based on signal processing and extraction, a model for the automatic and objective counting of CMS is proposed. The position and shape information of the striae on the bullet land is represented by a feature profile, which is used for determining the CMS number automatically. Rapid counting of CMS number provides a basis for ballistics correlations with large databases and further statistical and probability analysis. Experimental results in this report using bullets fired from ten consecutively manufactured barrels support this developed model.
