FRFDet: Efficient UAV Small Object Detection with Symmetric Sampling and Scalable Fusion
This work proposes FRFDet, a lightweight yet effective single-stage detector tailored for UAV-based small object detection, and proposes two plug-and-play modules: Inverse Bidirectional Sampling (IBS) and Scale-Feature Relationship Cross-Fusion (SFRCF).
