Proximity-CLIP: Text-Guided Semantic Proximity Learning for Zero-Shot Anomaly Detection

Vision-language models offer a promising approach for zero-shot anomaly detection (ZSAD). However, due to object-centric bias, normal and anomalous text prototypes exhibit a high semantic overlap. While enforcing strict orthogonality between them improves discriminability, mapping highly contiguous visual inputs onto d...

TempoGround: State-Aware Streaming Visual Grounding with Vision-Language Models

A VLM-native framework that detects cross-frame object correspondence and explicitly models object presence states, thereby enabling accurate and consistent visual grounding under streaming inputs, and introduces Streaming Grounding Reinforcement (SGR), which optimizes TempoGround with verifiable Grounding, Identity, a...
