Boosting Infrared Small Target Detection via Logit-Domain Contrast and Adaptive Shape Refinement
Handong Zeng, Zhengeng Yang, Shuai Zhang, Shikai Chen, Hongshan Yu
Infrared small target detection (IRSTD) remains challenging due to tiny target size, low signal-to-noise ratio, severe foreground-background imbalance, and blurred boundaries in complex scenes. Existing methods usually rely on post-activation probability-domain supervision for di…
