LIRS-YOLO: A Lightweight YOLO-Based Method for Infrared Features and Small Object Detection (opens in new tab)

Target detection in uncrewed aerial vehicle (UAV)-based infrared imagery plays a critical role in personnel search and rescue, security surveillance, and disaster monitoring. However, infrared targets captured from UAV platforms are often small, low-contrast, and weakly textured, and they exhibit significant scale variations due to constraints on flight altitude and viewing perspective. These challenges hinder accurate feature extraction and degrade detection performance, severely limiting th...
