AI for Security Firearms Detection

Our firearms detection technology utilizes AI to enhance threat detection by identifying firearms and localizing firearm carriers. We explore the forefront of AI-powered security, where innovation meets public safety through proactive firearm detection with advanced algorithms.

a. Detection and Localization of Firearm Carrier Persons

We develop an innovative approach for detecting and accurately localizing individuals carrying firearms in images or videos, specifically addressing challenges posed by clutter and diverse firearm shapes in complex environments. Our proposed method leverages human–firearm interaction information and incorporates an attention mechanism to discern relevant areas within the images or videos. A saliency-driven locality-preserving constraint is introduced to facilitate learning essential features while preserving foreground information. The utilization of attention mechanisms and saliency-driven locality preservation marks significant advancements in firearm localization and identification, offering enhanced capabilities for security and surveillance applications. A dataset containing thousands of annotated firearm carrier images is also prepared.

b Visual Firearms Detection and Localization

We develop an innovative algorithm for automatic firearm detection, specifically addressing challenges posed by variations in shape, size, and appearance of firearms. In contrast to existing object detectors, we use axis-aligned bounding boxes for training, and we predict oriented bounding boxes during the detection phase. We have also developed a firearm training dataset containing around 6000 annotated firearm images.

c. Improving security surveillance by hidden cameras

In this study our focus will be to develop the text highlights challenges in security surveillance, particularly the vulnerability of traditional cameras due to their visible locations, which can be exploited by criminals. To address this issue, the paper proposes an innovative solution involving hidden cameras strategically positioned to capture video through narrow regions, such as window curtain slits. The presented framework is effective and robust, automatically extracting slit regions and seamlessly merging them across frames to construct a panoramic view. The system successfully tackles challenges such as sudden illumination variations, demonstrating its effectiveness through experiments on various real video sequences. Importantly, it outperforms existing commercial software in the perceptual quality of the resulting panoramic images, showcasing the potential of this solution for enhancing security surveillance in discreet and effective ways.
