SFC-DETR: a small object detection model for drone images based on spatial and frequency domain collaborative enhancement
A frequency-augmented polarity-aware attention module (FAPAM) that combines polarity-aware attention with adaptive frequency domain enhancement (SFC-DETR) is introduced that outperforms state-of-the-art models in small object detection tasks.
