This work presents a novel automatic handgun detection system in\nvideos appropriate for both, surveillance and control purposes. We reformulate\nthis detection problem into the problem of minimizing false positives and solve\nit by building the key training data-set guided by the results of a deep\nConvolutional Neural Networks (CNN) classifier, then assessing the best\nclassification model under two approaches, the sliding window approach and\nregion proposal approach. The most promising results are obtained by Faster\nR-CNN based model trained on our new database. The best detector show a high\npotential even in low quality youtube videos and provides satisfactory results\nas automatic alarm system. Among 30 scenes, it successfully activates the alarm\nafter five successive true positives in less than 0.2 seconds, in 27 scenes. We\nalso define a new metric, Alarm Activation per Interval (AApI), to assess the\nperformance of a detection model as an automatic detection system in videos.","url_abs":"http://arxiv.org/abs/1702.05147v1","url_pdf":"http://arxiv.org/pdf/1702.05147v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"automatic-handgun-detection-alarm-in-videos","repo_url":"https://github.com/SihamTabik/Pistol-Detection-in-Videos","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":{"status":"ok"}}],"tasks":[{"task_slug":"deep-learning","task_name":"Deep Learning"},{"task_slug":"region-proposal","task_name":"Region Proposal"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=1702.05147","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
