Spatial-Frequency Enhancement and Scale-Decoupled Refinement Network for Salient Object Detection in ORSI (opens in new tab)

Optical remote sensing image salient object detection (ORSI-SOD) focuses on identifying and localizing visually distinctive regions within complex scenes characterized by intricate structures and cluttered backgrounds. This task presents significant challenges due to substantial scale variations among objects, inherent ambiguity in target appearance, pervasive background noise interference, and edge degradation caused by shadow effects. To address these challenges, we propose a novel spatial-...
