PIVOT: Physics-Grounded Verification for AI-Generated Audio-Video Detection
PIVOT, a physics-grounded AIGC detector instantiated here for audio-video clips, that estimates physical quantities from video and audio, selects physical laws relevant to each clip, and verifies their measurable constraints, demonstrates the practical promise of physical-consistency verification as a structured and in...
