GenRecal: Generation after Recalibration from Large to Small Vision-Language Models

Byung-Kwan Lee, Ryo Hachiuma, Yong Man Ro +2

Recent advancements in vision-language models (VLMs) have leveraged large language models (LLMs) to achieve performance on par with closed-source systems like GPT-4V. However, depl…

DVSM: Decoder-only View Synthesis Model Done Right

Cheng Sun, Jaesung Choe, Min-Hung Chen +2

Recent Large View Synthesis Models (LVSMs) advocate an encoder-decoder architecture that separates reconstruction and rendering into distinct networks. We re-examine this design. T…

Agent Explorative Policy Optimization for Multimodal Agentic Reasoning

Minki Kang, Shizhe Diao, Ryo Hachiuma +4

Vision-language models with extended reasoning succeed on complex problems, but many real-world problems require external tools that internal reasoning alone often cannot resolve.…

Seeing Fast and Slow: Learning the Flow of Time in Videos

Yen-Siang Wu, Rundong Luo, Jingsen Zhu +6

How can we tell whether a video has been sped up or slowed down? How can we generate videos at different speeds? Although videos have been central to modern computer vision researc…

4D-RGPT: Toward Region-level 4D Understanding via Perceptual Distillation

Chiao-An Yang, Ryo Hachiuma, Sifei Liu +4

Despite advances in Multimodal LLMs (MLLMs), their ability to reason over 3D structures and temporal dynamics remains limited, constrained by weak 4D perception and temporal unders…

V2V-GoT: Vehicle-to-Vehicle Cooperative Autonomous Driving with Multimodal Large Language Models and Graph-of-Thoughts

Hsu-kuang Chiu, Ryo Hachiuma, Chien-Yi Wang +3

Current state-of-the-art autonomous vehicles could face safety-critical situations when their local sensors are occluded by large nearby objects on the road. Vehicle-to-vehicle (V2…
