Abstract

Fire disasters pose severe threats to human lives, ecological systems, and economic assets worldwide, making early and accurate detection crucial for timely disaster response. While deep learning-based methods have shown promise for fire monitoring, existing approaches face persistent challenges: edge blurring caused by smoke and adverse weather degrades localization accuracy, small fire sources are frequently missed due to insufficient pixel information, and flame-like backgrounds cause false alarms. Current CNN+Transformer architectures struggle to address these issues simultaneously while maintaining computational efficiency. To bridge this gap, we propose Detection Transformer-Adaptive Encoder-Mamba (DETR-AE-Mamba), a lightweight detection framework with three novel components: Mamba-Perceptron (Mamba-P), which processes features in both time and frequency domains to enhance edge extraction; Adaptive Fusion Encoder (AFE), which improves global perception for small object detection; and ELD-Decay-Varifocal-Loss, a dynamic loss function that enhances noise robustness. Experiments on the D-Fire dataset show that DETR-AE-Mamba improves precision by 3.4% over RT-DETR-R18 while reducing parameters by 54.2% (from 21.4M to 9.8M) and GFLOPs by 69.8% (from 56.9 to 17.2), demonstrating potential for fire detection and applications in other fields.
