GFCR-Net: Gradient-Guided and Frequency-Gated Context Refinement for Robust Ship Detection in Complex Optical Remote Sensing Images

Robust ship detection in remote sensing imagery is essential for aerial surveillance, yet it remains challenging under adverse environmental conditions such as fog, haze, thin clouds, and sea clutter, as well as in dense and crowded port scenes. Existing methods often suffer from ambiguous receptive fields due to large...
