Impostor: An Agent-Curated Benchmark for Realistic AIGC Manipulation Localization 事件

Impostor: An Agent-Curated Benchmark for Realistic AIGC Manipulation Localization arXiv:2606.04545v1 Announce Type: new Abstract: Recent advances in generative image editing have improved the realism and controllability of localized image manipulation, raising new challenges for image manipulation detection and localization (IMDL). However, existing IMDL benchmarks still have limitations in visual realism, manipulation diversity, and generator coverage, making it difficult to reflect recent tre
