Efficient Car Logo Detection via YOLOv8 and Attention Mechanism Fusion
摘要
Car logo detection is crucial for intelligent transportation systems. This paper compares attention mechanisms integrated into YOLOv8m for car logo detection, evaluating Efficient Channel Attention (ECA), SimAM, and their combination against a baseline YOLOv8m (95.2% mAP@0.5, 48.6% mAP@0.5:0.95, 79.3 GFLOPs). On a dataset of 5372 images, ECA achieves 94.5% mAP@0.5 and 50.2% mAP@0.5:0.95 with 79.1 GFLOPs, SimAM reaches 96.1% mAP@0.5 and 50.0% mAP@0.5:0.95 with 79.1 GFLOPs, and the combined approach attains 95.3% mAP@0.5 and 50.1% mAP@0.5:0.95 with 79.3 GFLOPs. All variants maintain real-time performance with inference speeds of 29.29 FPS (ECA), 28.69 FPS (SimAM), and 27.95 FPS (combined), compared to the baseline’s 28.32 FPS on an NVIDIA RTX 3050 laptop GPU. These results demonstrate that integrating lightweight attention mechanisms can substantially enhance detection performance in data-constrained scenarios while preserving real-time efficiency.
