Aymane El Mandili, He Xu . ACMA: An Adaptive Conditional Model Activation Framework for Efficient Real-Time Fire Detection on Edge Devices. International Journal of Computer Applications. 187, 79 ( Feb 2026), 14-23. DOI=10.5120/ijca2026926342
Abstract
Real-time fire detection on edge devices presents significant computational challenges. Existing solutions struggle to balance detection accuracy with efficiency in resource-constrained environments. This paper introduces Adaptive Conditional Model Activation (ACMA), a novel conditional execution framework that optimizes deep learning deployment through dynamic model gating. The proposed approach employs multi-color space analysis and scene-aware adaptive thresholding to selectively activate YOLO model only when preliminary fire indicators exceed dynamically calculated thresholds. Experimental results demonstrate that ACMA achieves 77% filtering accuracy with only a 3.2% system-level accuracy reduction compared to continuous YOLO. While CPU usage reduction appears modest (5%) on severely constrained hardware like Raspberry Pi 4B where baseline utilization is already saturated it enables a transformative throughput to increase from 0.14 to 38 FPS, a 270× improvement. On a desktop i5 CPU, ACMA reduces usage by 80% and increases FPS by 25 times.
