Exacerbated by factors including sensor calibration errors, target motion, or thermal deformation, spatial misalignment frequently arises, resulting in structural distortion and edge ghosting in image fusion outcomes. To address these challenges, we propose the Bayesian Multi-Scale Registration (BMSR) method—a single-stage end-to-end framework designed for accurate infrared–visible image registration. The core of BMSR lies in its single-stage coarse-to-fine registration mechanism. By dynamically weighting and fusing features across various scales, this mechanism enables continuous optimization from global coarse registration to local fine registration within a single-stage network, thereby effectively mitigating the impact of modal discrepancies. Specifically, this framework consists of three key components: the Bayesian Predict Flow (BPF) module, the Multi-Scale Fusion (MSF) module, and the Progressive Feature Refinement (PFR) module. The BPF module quantifies predictive uncertainty, while the MSF module aligns multi-scale deformation field samples to produce a globally consistent, high-precision deformation field. The PFR module refines multimodal features via channel attention and dynamically adjusted spatial weights to enhance multimodal feature consistency. Collectively, these components constitute a closed-loop collaborative mechanism encompassing ”probabilistic deformation field generation – multi-scale fusion – feature refinement”, thereby collectively enabling accurate estimation of the final deformation field. Extensive experimental results demonstrate that BMSR outperforms SOTA registration networks in multi-modal image registration tasks.</div></div>","PeriodicalId":13549,"journal":{"name":"Infrared Physics & Technology","volume":"155 ","pages":"Article 106484"},"PeriodicalIF":3.4,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147386212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent learning-based BRDF models, including CNN, Transformer, and factorization-based architectures, improve angular fitting flexibility but still lack explicit physical constraints.

First, asymmetric broadening and multi-peak structures are used to capture complex directional distributions. Second, the parameter network leverages physical priors to generate parameter fields while enforcing constraints of non-negativity and energy conservation.

To address this issue, we propose a novel Hierarchical Feature Information Exchange Network (HFIENet), which comprises two main components: the Information Exchange (IE) module and the Selective Feature Fusion (SFF) module. The IE module employs the cross-attention strategy and differential weighting operation to perform information exchange, thereby enabling the network to extract more significant and comprehensive features from each modality. Due to the different importance of shallow and deep features, the SFF module adaptively integrates essential features for image reconstruction by leveraging attention mechanisms across both channel and spatial dimensions.
