Code-in-the-Loop Forensics: Agentic Tool Use for Image Forgery Detection

ArXi:2512.16300v2 Announce Type: replace Existing image forgery detection (IFD) methods either exploit low-level, semantics-agnostic artifacts or rely on multimodal large language models (MLLMs) with high-level semantic knowledge. Although naturally complementary, these two information streams are highly heterogeneous in both paradigm and reasoning, making it difficult for existing methods to unify them or effectively model their cross-level interactions.
