FLINet: Fuzzy Logic for Infrared Small-Target Detection (opens in new tab)

Infrared small-target detection (IRSTD) remains challenging due to weak target responses, cluttered backgrounds, and large variations in target appearance. In this article, we propose FLINet, a fuzzy-logic-guided network that introduces a fuzzy set perspective for uncertainty-aware feature fusion in infrared small-target detection. FLINet follows a U-shaped encoder–decoder architecture and incorporates two key modules: a global–local fuzzy (GLF) computation module and a difference-aware featu...
