Advances in Firearm Identification

Several recent studies have called for improved imaging technology and matching algorithms to support firearm identification. In this study, researchers investigated and developed a novel, accurate and low-cost system for structural 3D imaging and comparison of cartridge cases. The research demonstrated the system's potential for increasing the quality and reducing the cost of forensic analyses. The project combines the recently developed GelSight high-resolution surface topography imaging system with state-of-the-art algorithms for matching structural features. To read the report, Applied Research and Development of a Three-Dimensional Topography System for Imaging and Analysis of Striated and Impressed Tool Marks for Firearm Identification using GelSight, go to The report is the result of a project funded by the National Institute of Justice.
