PQGNet: Perceptual Query Guided Network for Infrared Small Target Detection (opens in new tab)

Infrared small target detection (IRSTD) holds critical importance for military security applications. Although U-shaped architectures have improved baseline performance, existing methods still suffer from two key limitations: 1) insufficient spatial perception for tiny targets leads to target location loss and 2) edge degradation and semantic ambiguity in deep feature reconstruction. To address these challenges, we propose PQGNet with the following contributions: To enhance capability of spat...
