Source-Face Authenticity Detection for 3D Gaussian Heads Reconstructed from a Single Portrait: A Benchmark and Dedicated Detector

This work introduces the first large-scale benchmark for this task by collecting real portraits and fake portraits from multiple sources and evaluates representative existing detectors on this benchmark, revealing their lack of explicit mechanisms for retaining fine-grained information and maintaining feature consisten...

GAP-SAM: A Global Artifact Prior for Generalizable AI-Generated Image Manipulation Localization

AI-generated image manipulation localization identifies edited pixels, but its OOD performance lags behind image-level detection partly because pixel supervision entangles forensic evidence with dataset-specific mask geometry and semantic boundaries. Extending image-level distribution alignment to localization, we cons...

Defake-o3: From Speculative Rationales to Verifiable Evidence for Explainable AIGI Detection

Defake-o3 is presented, an explainable AIGI detector that moves from speculative rationales to verifiable evidence, and Experiments show that Defake-o3 improves both detection accuracy and explanation quality, producing more localized, verifiable, and persuasive evidence.
