New VLM framework uses Bayesian inference for efficient expressway anomaly detection

Researchers have developed VIBES, a new framework for detecting anomalies in expressway surveillance videos. VIBES uses Vision-Language Models (VLMs) guided by Bayesian inference to efficiently identify subtle abnormal vehicle motions in far-field targets. The system updates its understanding of normal driving behavior and uses this to trigger focused VLM analysis on specific regions, improving accuracy and reducing computational costs. AI
