Module-Specific Contributions
Ablation studies rigorously validate the effectiveness of each proposed module. The CSME backbone significantly improves precision, recall, and mAP50 while reducing parameters. EMSFFN enhances recall through adaptive multi-scale fusion. ASSA-AIFI improves mAP50 by focusing attention on critical defect regions. The combined integration of all modules yields the best overall performance, confirming their complementary contributions.

Acknowledged Limitations & Future Directions
Despite its strong performance, the study acknowledges limitations including a relatively limited dataset affecting generalization, unvalidated performance under extreme environmental conditions (rain, fog, strong winds), and potential challenges for deployment on resource-constrained edge devices regarding power and thermal management. Future work includes expanding datasets, lightweight optimization, and broader deployment validation.
Enhanced Defect Localization and Noise Suppression
Visual comparisons highlight CEA-DETR's superior capability in detecting fine cracks and early-stage peeling with higher confidence and precise bounding box localization, even in complex scenes with coexisting multi-scale defects. Compared to baseline models (YOLO variants, RT-DETR-r18), CEA-DETR significantly reduces false positives from background interference like grass or shadows.
Heatmap visualizations (Figure 9) further confirm that CEA-DETR focuses attention more intensely and accurately on core defect regions, suppressing irrelevant background noise. This refined focus is critical for reliable inspection in challenging industrial environments.
