The FBI DRUGFIRE Program entails the continuing phased development and deployment of a scalable automated firearms identification system. The first phase of this system, a networked, database-driven firearms evidence imaging system, has been operational for approximately one year and has demonstrated its effectiveness in facilitating the sharing and linking of firearms evidence collected in serial, gang, and drug-related shooting investigations. However, there is a pressing need for development of enhancements which will more fully automate the system so that it is capable of processing very large volumes of firearms evidence. These enhancements would provide automated image analysis and pattern matching functionalities. Existing `spin off' technologies need to be integrated into the present DRUGFIRE system to automate the 3-D mensuration, registration, feature extraction, and matching of the microtopographical surface features imprinted on the primers of fired casings during firing.
