Enhancing Target and Rectifying Clutter: A Structure-Guided Frequency Rectification Network for Infrared Small-Target Detection
Infrared small-target detection (IRSTD) remains challenging under low signal-to-noise ratio conditions, where weak target responses are easily submerged by complex background clutter. Existing enhancement-oriented methods may inadvertently activate target-like clutter in complex backgrounds. Once propagated through fea...
