Automatic identification of bullet signatures based on consecutive matching striae (CMS) criteria

摘要: The consecutive matching striae (CMS) numeric criteria for firearm and toolmark identifications have been widely accepted by forensic examiners, although there questions concerning its observer subjectivity limited statistical support. In this paper, based on signal processing extraction, a model the automatic objective counting of CMS is proposed. position shape information bullet land represented feature profile, which used determining number automatically. Rapid provides basis ballistics correlations with large databases further probability analysis. Experimental results in report using bullets fired from ten consecutively manufactured barrels support developed model.
