Algorithm evaluation demonstrates enhanced small-object detection accuracy across UAV aerial benchmarks, indicating improved edge deployment viability for aerial surveillance.

Key Points

To develop a lightweight, high-performance object detection model that overcomes small object scales, severe occlusion, and cluttered backgrounds in UAV aerial imagery.
Engineered MD-YOLO by integrating three lightweight modules (IMO, DS-SPPF, and HPConv) into the YOLO26 baseline to optimize backbone feature extraction, multi-scale contextual aggregation, and downsampling detail preservation.
Evaluated detection accuracy and computational complexity across three public aerial benchmarks: VisDrone-2019, UAVDT, and NWPU VHR-10.
On the VisDrone-2019 dataset, MD-YOLO improved Precision by 3.9, Recall by 3.2, mAP50 by 2.9, and mAP50-95 by 3.1 percentage points relative to the baseline while maintaining a parameter count of 9.3 million.
Independent evaluations on the UAVDT and NWPU VHR-10 datasets yielded mAP50 improvements of 8.3 and 1.4 percentage points, respectively.
