A network is trained to classify these paired-bounding-boxes into human carrying the identified firearm or not. ...
Each detected human is paired with each detected firearm, allowing us to create a paired bounding box that contains both object and the human. ...
This paper introduces first such method which uses human and hand detection followed by firearm detection to identify firearm carriers in crowded scenes. ...

To address this problem, we propose a novel approach that leverages human-firearm interaction information, which provides valuable clues for localizing firearm carriers. ...
Our approach incorporates an attention mechanism that effectively distinguishes humans and firearms from the background by focusing on relevant areas. ...
The main contributions of our work are as follows: • We propose a novel deep learning architecture that effectively identifies localized firearm carriers by incorporating human-firearm instance pair detection ...
