Low-frequency components are fused via a multi-layer strategy, while high-frequency components are merged using an integrated weighting scheme enhanced by guided filtering.

To address these limitations, we propose the Two-Stage Nested U-Network (TSNUNet), which incorporates three innovative modules. First, the Pixel Shuffle Channel Convert Module (PSCCM) captures the potential cross-channel information distribution in high-level features, aligns multi-level features, and ensures accurate and complete initial predictions. Second, the Two-Stage Strategy, with its hybrid connections and a Two-Stage Fusion Module (TSFM), facilitates interactive learning across stages and directs precise location cues, further boosting prediction accuracy. Third, we design the Nested U/Trans-U Module for robust cross-level feature decoding. The Nested U/Trans-U Module employs continuous pixel unshuffle down-sampling, hierarchical adaptive top-layer enhancement, and multi-level pixel shuffle feature reconstruction, specifically contributing to improved feature representation and accuracy. Finally, through our Two-Stage combined supervision mechanism, TSNUNet is capable of effectively segmenting both complete and accurate salient objects. Experiments on 7 SOD and 4 cross-domain datasets show TSNUNet outperforms state-of-the-art methods with strong generalization capability.

Since hand details play a crucial role in conveying human posture, accurate hand reconstruction is of great importance for applications in 3D human modeling. However, precise recovery of hands is highly challenging due to the relatively small spatial proportion of hands, high flexibility, diverse gestures, and frequent occlusions. In this work, we propose a lightweight whole-body mesh recovery framework that enhances hand detail reconstruction while reducing computational complexity. Specifically, we introduce a Joints and Depth Aware Fusion (JDAF) module that adaptively encodes geometric joints and depth cues from local hand regions. This module provides strong 3D priors and effectively guides the regression of accurate hand parameters. In addition, we propose an Adaptive Dual-branch Pooling Attention (ADPA) module that models global context and local fine-grained interactions in a lightweight manner. Compared with the traditional self-attention mechanism, this module significantly reduces the computational burden. Experiments on the EHF and UBody benchmarks demonstrate that our approach outperforms SOTA methods, reducing body MPVPE by 8.5% and hand PA-MPVPE by 6.2%, while significantly lowering the number of parameters and MACs. More importantly, its efficiency and lightweight make it particularly suitable for real-time visual communication scenarios such as immersive conferencing, sign language translation, and VR/AR interaction.</div></div>","PeriodicalId":54755,"journal":{"name":"Journal of Visual Communication and Image Representation","volume":"116 ","pages":"Article 104729"},"PeriodicalIF":3.1,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146079534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this critical gap, we introduce SentinelFakeNet (SFNet), a novel framework specifically designed for detecting AI-generated military images.
