New algorithm improves object detection accuracy in UAV images, suggesting enhanced performance in complex scenarios.

This research aims to enhance object detection accuracy in UAV images, particularly for small objects and variable scales.
Developed DMA-YOLO algorithm based on YOLOv8s model including deep diverse branch block and multi-scale auxiliary feature.
Designed DF-C2f module for better small object feature extraction and a multi-scale pyramid network for feature fusion.
Optimized detection head and implemented EIoU loss for improved bounding box regression.
DMA-YOLO achieved a 3.7% increase in mAP50 and a 2.8% increase in mAP50:95 compared to the baseline.
Performance enhancements demonstrated with minimal impact on parameter counts and computational complexity.
Validation on RSOD dataset confirmed generalization capability across various data distributions.
