Text-Guided Visual Representation Optimization for Sensor-Acquired Video Temporal Grounding

Video temporal grounding (VTG) aims to localize a semantically relevant temporal segment within an untrimmed video based on a natural language query. The task continues to face challenges arising from cross-modal semantic misalignment, which is largely attributed to redundant visual content in senso...
