Breaking Alignment Barriers: TPS-Driven Semantic Correlation Learning for Alignment-Free RGB-T Salient Object Detection

Dec 25, 2025

To address the challenging problem of salient object detection (SOD) in unaligned RGB-T image pairs—characterized by spatial misalignment, scale discrepancies, and viewpoint shifts—this paper proposes the first alignment-free, lightweight cross-modal collaborative perception framework. Our method innovatively integrates a thin-plate spline (TPS)-driven spatial self-correction mechanism with a semantic correlation constraint-based joint learning paradigm. We design a dual-stream MobileViT-Mamba architecture incorporating three key components: a TPS Alignment Module (TPSAM), a Semantic Correlation Constraint Module (SCCM), and a Cross-Modal Correlation Module (CMCM), enabling deep semantic alignment and efficient sequence modeling. Evaluated on multiple unaligned benchmarks, our approach achieves state-of-the-art performance among lightweight RGB-T SOD methods, significantly outperforming mainstream approaches reliant on manual registration. Moreover, it reduces model parameters and computational cost by over 40%.
