Software Application), are presented. MEDUSA brings together two approaches to facilitate the design of an automatic,
CCTV-based firearm detection system: psychological—to elicit strategies used by CCTV operators; and machine
vision—to identify key cues derived from camera imagery. Potentially effective human- and machine-based strategies
have been identified; these will form elements of the final system. The efficacies of these algorithms have been tested on
staged CCTV footage in discriminating between firearms and matched distractor objects. Early results indicate the
potential for this combined approach.
