Efficient Spatio-Temporal Grounding with Multimodal Large Models via Second-Level Tracking and RL Verification
arXiv:2606.29023v1 Announce Type: cross Abstract: Spatio-temporal grounding in long videos requires precise temporal localization and robust object tracking conditioned on natural-language queries. While recent vision-language models (VLMs) show strong reasoning ability, directly applying frame-by-frame inference to long sequences is computationally expensive and unstable. We propose a practical pipeline that shifts from frame-level to second-level tracking and performs cross-second smoothing to preserve continuity while reducing sequence length. To improve reasoning supervision, we synthesize
This development addressing the computational expense and instability of spatio-temporal grounding in long videos is emerging as multimodal large models (VLMs) become more sophisticated and demand more efficient processing techniques.
Improving the efficiency and stability of video understanding technologies will unlock new capabilities for AI agents to interact with dynamic real-world environments more effectively, crucial for automation and complex task execution.
The computational approach to spatio-temporal grounding shifts from frame-by-frame to second-level tracking, significantly reducing processing overhead and improving continuity in long video analysis for AI systems.
