| dc.description.abstract | Oil palm plantation monitoring requires accurate tree detection for yield estimation, resource allocation, and sustainability compliance, yet manual counting methods remain labour-intensive and error-prone at scale. Despite growing adoption of UAV-based deep learning detection, no study has systematically compared the latest CNN-based and transformer-based paradigms under identical conditions for oil palm tree detection. This study fine-tunes and comparatively evaluates YOLOv11 (CNN-based) and D-FINE (transformer-based) using 6,080 high-resolution UAV images containing 111,810 annotated trees from Penang, Malaysia, across standardised GPU and CPU platforms. YOLOv11 achieved higher precision (0.953), mAP@0.5 (0.988), and faster inference (20.61 FPS on GPU) with a compact 109.1 MB footprint, favouring real time and resource-constrained deployments. D-FINE achieved higher recall (0.977) and superior robustness under adverse conditions: in compound scenarios combining dense canopy layouts with motion blur, YOLOv11 suffered a 34% reduction in detections while D-FINE maintained performance with only a 5% reduction. These findings establish that YOLOv11 is preferable for real-time monitoring under favourable imaging conditions, while D-FINE better serves scenarios demanding detection consistency under dense canopy overlap and motion-degraded imagery, providing empirical guidance for architecture selection in UAV-based oil palm plantation monitoring. | |
