To address this challenge, we propose a detection framework that integrates adaptive spectrum masking and cross-scale feature fusion, termed Masked Spectrum Vision Transformer with Cross-scale Fusion (MSViT-CF). Our approach introduces two key innovations: (1) Multi-band Artifact Enhancement Module (MAEM) reconstructs input images through wavelet decomposition and strategically perturbs high-frequency subbands via adaptive masking, amplifying subtle forgery traces while forcing the model to learn generalized artifact representations; (2) Dynamic Scale Fusion Transformer (DSFT) integrates multi-resolution frequency features through parallel convolutional-transformer pathways, dynamically weighting local spectrum anomalies and global structural inconsistencies. MAEM enhances artifact sensitivity through frequency-space discrepancy learning, while DSFT establishes cross-scale relationships between pixel-level irregularities and semantic-level inconsistencies via learnable attention gates. Experimental results demonstrate that MSViT-CF significantly outperforms existing state-of-the-art methods in detecting deepfake images generated by various GANs and diffusion models, exhibiting superior universality and robustness.<\/jats:p>","DOI":"10.3233\/faia251141","type":"book-chapter","created":{"date-parts":[[2025,10,22]],"date-time":"2025-10-22T09:52:38Z","timestamp":1761126758000},"source":"Crossref","is-referenced-by-count":1,"title":["Masked Spectrum ViT with Cross-Scale Fusion for Universal Deepfake Detection"],"prefix":"10.3233","author":[{"given":"Kaiwen","family":"Xu","sequence":"first","affiliation":[{"name":"School of Computer Science and Engineering, Nanjing University of Science and Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiyuan","family":"Hu","sequence":"additional","affiliation":[{"name":"School of Computer Science, Beijing University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chen","family":"Chen","sequence":"additional","affiliation":[{"name":"Institute of Automation, Chinese Academy of Sciences"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yichao","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Nanjing University of Science and Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yang","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Nanjing University of Science and Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7437","container-title":["Frontiers in Artificial Intelligence and Applications","ECAI 2025"],"original-title":[],"link":[{"URL":"https:\/\/ebooks.iospress.nl\/pdf\/doi\/10.3233\/FAIA251141","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,22]],"date-time":"2025-10-22T09:52:39Z","timestamp":1761126759000},"score":1,"resource":{"primary":{"URL":"https:\/\/ebooks.iospress.nl\/doi\/10.3233\/FAIA251141"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,10,21]]},"ISBN":["9781643686318"],"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/faia251141","relation":{},"ISSN":["0922-6389","1879-8314"],"issn-type":[{"value":"0922-6389","type":"print"},{"value":"1879-8314","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,10,21]]}}}
